bash-completion: add bits to dist tarball
The bits command was added in commit 6e1301d59 (text-utils: add bits
command) but the bash-completion file was not added to the autotools
Makemodule.am, causing it to be missing from release tarballs.
This resulted in meson build failures when using the tarball with
bash-completion installed, as meson.build references the file but
it doesn't exist in the tarball.

libblkid: Fix probe_ioctl_tp assigning BLKGETDISKSEQ as physical sector size
Fix issue introduced by PR#2908 in probe_ioctl_tp where the BLKGETDISKSEQ ioctl
result is incorrectly assigned to the topology with
blkid_topology_set_physical_sector_size instead of blkid_topology_set_diskseq.
This issue was observed while using a Debian 13 container on a RHEL 9.4 host
attempting to format a volume. The physical sector size was incorrectly
reported as 3. This issue also presents with the fdisk command,
which also uses this library to resolve physical sector size of devices.
(Mentioning -u instead of -n, and falsely claiming emptiness.)
Now the above command will report:
blkid: invalid argument: no
(I don't think option -n needs to be mentioned, as it will be obvious
when inspecting the command line. Not mentioning the option allows
reusing an existing error message, avoiding needless ballooning and
allowing the patch to be applied to the stable branch.)

libmount: don't report fsconfig errors with "nofail"
The new kernel API returns EINVAL on FSCONFIG_CMD_CREATE if the mount
source is inaccessible. We do not want to report this as an error when
the "nofail" mount option is specified.
Note that EINVAL may also be returned by other fsconfig() settings, so
we need to check whether a source is specified and whether it is really
inaccessible. This is just a heuristic (as with the old mount(2)).

libfdisk: (script) fix device name separator parsing
In the named-fields script format, the colon is used as the separator
between the device name and other values. The device name may also

zramctl: ignore ENOENT when setting max_comp_streams

zramctl: fix MEM-USED column description
The MEM-USED column was incorrectly documented as showing current
memory consumption. This is due to confusing naming in the kernel's
zram implementation:
- Kernel field "mem_used_total" (3rd in mm_stat) = current memory usage
- Kernel field "mem_used_max" (5th in mm_stat) = peak memory usage
zramctl maps these as:
- TOTAL column <= mem_used_total (current usage)
- MEM-USED column <= mem_used_max (peak usage)
The misleading "MEM-USED" name suggests current usage, but it actually
shows the peak memory usage (high water mark) since device creation
or last reset. This is tracked by the kernel's max_used_pages which
only increases when current usage exceeds the stored maximum.
Fixed description from:
"memory zram have been consumed to store compressed data" to
"peak memory usage to store compressed data".

hardlink: fix performance regression (inefficient signal evaluation)
During work on better verbose output, I found a regression between
v2.40 and v2.41 (and v2.42). In the new version, hardlink is 3-4 times
slower.
The problem is in the function where we verify signals. It calls the
function signal() even though no signal is delivered. It's called in
code loops where hardlink scans files, making it a performance-sensitive
area.
Another significant performance improvement is using an inline function
for handle_interrupt().
This simple patch improves hardlink performance by 10 times.
