bcachefs: Prep work for variable size btree node buffers
bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.
And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.
Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.

In __bch2_ioctl_subvolume_create(), we grab s_umount unconditionally
and unlock it at the end of the function. There is a comment
"why do we need this lock?" about the lock coming from
commit 42d237320e98 ("bcachefs: Snapshot creation, deletion")
The reason is that __bch2_ioctl_subvolume_create() calls
sync_inodes_sb() which enforce locked s_umount to writeback all dirty
nodes before doing snapshot works.
Fix it by read locking s_umount for snapshotting only and unlocking
s_umount after sync_inodes_sb().

No point in allocating a new mm, counting arguments and environment

This patch does expose the fact that 'do_filp_open()' that execve() uses
is still unnecessarily expensive in the failure case, because it
allocates the 'struct file *' early, even if the path lookup (which is
heavily optimized) fails.
So that remains an unnecessary cost in the "no such executable" case,

- Associate samples that identify loads and stores with data
structures. This uses events available on Intel, AMD and others and
DWARF info:
# To get memory access samples in kernel for 1 second (on Intel)
$ perf mem record -a -K --ldlat=4 -- sleep 1
# Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
$ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1

This uses the existing annotate code, calling objdump to do the
disassembly, with improvements to avoid having this take too long,
but longer term a switch to a disassembler library, possibly
reusing code in the kernel will be pursued.
This is the initial implementation, please use it and report
impressions and bugs. Make sure the kernel-debuginfo packages match
the running kernel. The 'perf report' phase for non short perf.data
files may take a while.
There is a great article about it on LWN:
https://lwn.net/Articles/955709/ - "Data-type profiling for perf"
One last test I did while writing this text, on a AMD Ryzen 5950X,
using a distro kernel, while doing a simple 'find /' on an
otherwise idle system resulted in:
- Add s390 raw data interpretation for PAI (Processor Activity
Instrumentation) counters.
perf archive:
- Add new option '--all' to pack perf.data with DSOs.
- Add new option '--unpack' to expand tarballs.
Initialization speedups:
- Lazily initialize zstd streams to save memory when not using it.
- Lazily allocate/size mmap event copy.
- Lazy load kernel symbols in 'perf record'.
- Be lazier in allocating lost samples buffer in 'perf record'.
- Don't synthesize BPF events when disabled via the command line
(perf record --no-bpf-event).
Assorted improvements:
- Show note on AMD systems that the :p, :pp, :ppp and :P are all the
same, as IBS (Instruction Based Sampling) is used and it is
inherentely precise, not having levels of precision like in Intel
systems.
- When 'cycles' isn't available, fall back to the "task-clock" event
when not system wide, not to 'cpu-clock'.
- Add --debug-file option to redirect debug output, e.g.:
$ perf --debug-file /tmp/perf.log record -v true
- Shrink 'struct map' to under one cacheline by avoiding function
pointers for selecting if addresses are identity or DSO relative,
and using just a byte for some boolean struct members.
- Resolve the arch specific strerrno just once to use in
perf_env__arch_strerrno().
- Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.
Assorted fixes:
- Fix the default 'perf top' usage on Intel hybrid systems, now it
starts with a browser showing the number of samples for Efficiency
(cpu_atom/cycles/P) and Performance (cpu_core/cycles/P). This
behaviour is similar on ARM64, with its respective set of
big.LITTLE processors.
- Fix segfault on build_mem_topology() error path.
- Fix 'perf mem' error on hybrid related to availability of mem event
in a PMU.
- Fix missing reference count gets (map, maps) in the db-export code.
- Avoid recursively taking env->bpf_progs.lock in the 'perf_env'
code.
- Use the newly introduced maps__for_each_map() to add missing
locking around iteration of 'struct map' entries.
- Parse NOTE segments until the build id is found, don't stop on the
first one, ELF files may have several such NOTE segments.
- Remove 'egrep' usage, its deprecated, use 'grep -E' instead.
- Warn first about missing libelf, not libbpf, that depends on
libelf.
- Use alternative to 'find ... -printf' as this isn't supported in
busybox.
- Address python 3.6 DeprecationWarning for string scapes.
- Fix memory leak in uniq() in libsubcmd.
- Fix man page formatting for 'perf lock'
- Fix some spelling mistakes.
perf tests:
- Fail shell tests that needs some symbol in perf itself if it is
stripped. These tests check if a symbol is resolved, if some hot
function is indeed detected by profiling, etc.
- The 'perf test sigtrap' test is currently failing on PREEMPT_RT,
skip it if sleeping spinlocks are detected (using BTF) and point to
the mailing list discussion about it. This test is also being
skipped on several architectures (powerpc, s390x, arm and aarch64)
due to other pending issues with intruction breakpoints.
- Adjust test case perf record offcpu profiling tests for s390.
- Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest,
addressing issues caused by the fallback from cycles to task-clock
done in this release.
- Fix mask for VG register in the user-regs test.
- Use shellcheck on 'perf test' shell scripts automatically to make
sure changes don't introduce things it flags as problematic.
- Add option to change objdump binary and allow it to be set via
'perf config'.
- Add basic 'perf script', 'perf list --json" and 'perf diff' tests.
- Basic branch counter support.
- Make DSO tests a suite rather than individual.
- Remove atomics from test_loop to avoid test failures.
- Fix call chain match on powerpc for the record+probe_libc_inet_pton
test.
- Improve Intel hybrid tests.

to replace their own implementations. Both afs and 9p are ported. cifs

The overal goal is to get high-level I/O and knowledge of the page
cache and ouf of the filesystem drivers. This includes knowledge about
the existence of pages and folios
The pull request converts afs and 9p. This removes about 800 lines of
code from afs and 300 from 9p. For 9p it is now possible to do writes
in larger than a page chunks. Additionally, multipage folio support
can be turned on for 9p. Separate patches exist for cifs removing
another 2000+ lines. I've included detailed information in the
individual pulls I took.
Summary:
- Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
calls to prevent these from happening at the same time.
- Support for direct and unbuffered I/O.
- Support for write-through caching in the page cache.
- O_*SYNC and RWF_*SYNC writes use write-through rather than writing
to the page cache and then flushing afterwards.
- Support for write-streaming.
- Support for write grouping.
- Skip reads for which the server could only return zeros or EOF.
- The fscache module is now part of the netfs library and the

cifs: handle servers that still advertise multichannel after disabling
Some servers like Azure SMB servers always advertise multichannel
capability in server capabilities list. Such servers return error
STATUS_NOT_IMPLEMENTED for ioctl calls to query server interfaces,
and expect clients to consider that as a sign that they do not support
multichannel.
We already handled this at mount time. Soon after the tree connect,
we query server interfaces. And when server returned STATUS_NOT_IMPLEMENTED,
we kept interface list as empty. When cifs_try_adding_channels gets
called, it would not find any interfaces, so will not add channels.
For the case where an active multichannel mount exists, and multichannel
is disabled by such a server, this change will now allow the client
to disable secondary channels on the mount. It will check the return
status of query server interfaces call soon after a tree reconnect.
If the return status is EOPNOTSUPP, then instead of the check to add
more channels, we'll disable the secondary channels instead.
For better code reuse, this change also moves the common code for
disabling multichannel to a helper function.

Reason for this is that get_idle_time() in fs/proc/stat.c has different
sources for both values depending on if a CPU is online or offline:
- if a CPU is online the values may be taken from its per cpu
tick_cpu_sched structure
- if a CPU is offline the values are taken from its per cpu cpustat
structure
The problem is that the per cpu tick_cpu_sched structure is set to zero on
CPU offline. See tick_cancel_sched_timer() in kernel/time/tick-sched.c.
Therefore when a CPU is brought offline and online afterwards both its idle
and iowait sleeptime will be zero, causing a jump backward in total system
idle and iowait sleeptime. In a similar way if a CPU is then brought
offline again the total idle and iowait sleeptimes will jump forward.
It looks like this behavior was introduced with commit 4b0c0f294f60
("tick: Cleanup NOHZ per cpu data on cpu down").
This was only noticed now on s390, since we switched to generic idle time
reporting with commit be76ea614460 ("s390/idle: remove arch_cpu_idle_time()
and corresponding code").
Fix this by preserving the values of idle_sleeptime and iowait_sleeptime
members of the per-cpu tick_sched structure on CPU hotplug.

The src_inc and dst_inc members of 'struct dma_interleaved_template' are

cifs: pick channel for tcon and tdis
Today, the tree connect and disconnect requests are
sent on the primary channel only. However, the new
multichannel logic allows the session to remain active
even if one of the channels are alive. So a tree connect
can now be triggered during a reconnect on any of
its channels.
This change changes tcon and tdis calls to pick an
active channel instead of the first one.

cifs: open_cached_dir should not rely on primary channel
open_cached_dir today selects ses->server a.k.a primary channel
to send requests. When multichannel is used, the primary
channel maybe down. So it does not make sense to rely only
on that channel.
This fix makes this function pick a channel with the standard
helper function cifs_pick_channel.
