The normal journald functions add the location in the C source code files to
the log messages. This is nice for a big C based project, but logger is used in
scripts so it would be more useful to let users specify the location in the
script by adding the CODE_FUNC, CODE_FILE and CODE_FILE fields to the log
message.
It is already possible to do this, but it will result in two versions of these
fields: one for the location in logger.c and one for the location in the
script.
partx: exit with error code when partition read failed
Make sure partx exits with a non-0 return code when
it runs into either code-path where getting the partition
table failed (or wasn't even attempted because of previous
error condition).
Change was tested using:
touch /tmp/foobar
partx -s - /tmp/foobar
Previously that was only printing an error/warning message
and then exiting with 0, but after this change it exits
with 1.

blkzone: fix whole device detection
Matias Bjørling wrote:
The current detection code for chunk size assumes that the
underlying device is a device that uses the minor device id
as the partition id, and that the whole device has minor id 0.
This is not true for example null_blk and nvme device drivers.
Let's use sysfs_devno_to_wholedisk() to get whole-disk devno.

The POSIX standard states that poll(3P) is being made available by
<poll.h>, not <sys/poll.h>. Most commands already include the correct
header, with the exception of rfkill. Fix that to avoid a warning on
musl-based systems.
The header <ncursesw/ncurses.h> defines the get_wch(3) function only
when `NCURSES_WIDECHAR` is defined. This define is actually getting set
in the same header file, but only in case `_XOPEN_SOURCE` is defined and
has a value of 500 or higher. As we already have the precedence of
defining `_XOPEN_SOURCE` to a value of 600 in some other files, simply
define it to the minimum required value of 500 in "cfdisk.c". This
silences a warning for `get_wch` being unknown.

libmount: fix mnt_table_is_fs_mounted() for NFS bind mounts.
When you bind-mount a subdirectory of a local filesystem, the
path to that subdirectory appears as the fourth field in mountinfo.
For nfs mounts, the fourth field is always "/", and the subdirectory
part is appended to the "special" (aka "device") field. This is
consistent with historical NFS usage which always includes a path in
the fs_spec field.
libmount needs to know about this when "mount -a" checks to see if
a filesystem is already mounted.

lsmem: fix total online/offline memory calculation
lsmem currently calculates the total online/offline memory by iterating
over all lsmem->blocks. Depending on the lsmem options, there may be
only one lsmem->block, because all sysfs memory blocks could be merged
into one. In this case, the calculation is wrong, because the individual
online/offline state of the sysfs memory blocks is not preserved, but
rather lsmem->blocks[0].state is set to the state of the first sysfs
memory block, typically MEMORY_STATE_ONLINE (at least on s390).
This means that "Total offline memory" will always be calculated as 0
in such cases, e.g. when using "lsmem --summary", or any options that
would merge the table output to one line, like "lsmem -o RANGE":
~# lsmem --summary
Memory block size: 1G
Total online memory: 20G
Total offline memory: 0B
Adding the "-a" option shows the real summary, since there is no block
merging going on, and the calculation is therefore correct:
~# lsmem -a --summary
Memory block size: 1G
Total online memory: 16G
Total offline memory: 4G
Fix this by moving the online/offline calculation into the loop that
is iterating over all sysfs memory blocks, instead of iterating over
potentially merged lsmem->blocks.
