sfdisk: only report I/O errors on --move-data
Now sfdisk stops everything on I/O error when moving data. It seems
better to report the error to user and continue as it's better to have
one bad sector in the partition than inconsistent all partition.

libmount: do not unnecessarily chmod utab.lock
Before ecfeae90a294 ("libmount: Ensure utab.lock mode 644"), you could do
something like:
irc:/tmp umount --version
umount from util-linux 2.27.1 (libmount 2.27.0: selinux, assert, debug)
irc:/tmp mkdir foo bar
irc:/tmp unshare -Urm
irc:/tmp mount --bind foo bar
irc:/tmp umount bar
irc:/tmp echo $?
0
However, afterwards, you get:
/tmp unshare -Urm
/tmp mount --bind foo bar
/tmp umount bar
umount: /tmp/bar: filesystem was unmounted, but failed to update userspace mount table.
Because of the chmod failing:
fchmod(3, 0644) = -1 EPERM (Operation not permitted)
Let's figure out whether the chmod is necessary before doing it, and only
do it if it is necessary. This won't fix cases where the system is already
broken, but at least on healthy systems umount will behave as before.
This PR fixes an off by one in `strncmp(dev->bid_name, "/dev/mapper/", 11)` check. The `"/dev/mapper/"` string literal has a length of 12 and without this fix paths like `"/dev/mapperSOMETHING"` would also be accepted.

______________________________________________________
GNU C Library NEWS -- history of user-visible changes.
Version 2.31
Deprecated and removed features, and other changes affecting compatibility:
* The settimeofday function can still be used to set a system-wide time
zone when the operating system supports it. This is because the Linux
kernel reused the API, on some architectures, to describe a system-wide
time-zone-like offset between the software clock maintained by the kernel,
and the "RTC" clock that keeps time when the system is shut down.
However, to reduce the odds of this offset being set by accident,
settimeofday can no longer be used to set the time and the offset
simultaneously. If both of its two arguments are non-null, the call
will fail (setting errno to EINVAL).
Callers attempting to set this offset should also be prepared for the call
to fail and set errno to ENOSYS; this already happens on the Hurd and on
some Linux architectures. The Linux kernel maintainers are discussing a
more principled replacement for the reused API. After a replacement
becomes available, we will change settimeofday to fail with ENOSYS on all
platforms when its 'tzp' argument is not a null pointer.
settimeofday itself is obsolescent according to POSIX. Programs that set
the system time should use clock_settime and/or the adjtime family of
functions instead. We may cease to make settimeofday available to newly
linked binaries after there is a replacement for Linux's time-zone-like
offset API.
______________________________________________________
hwclock(8) had one settimeofday(2) call where both args were set for
--hctosys when the RTC was ticking UTC. This allowed setting the system
time, timezone, and locking the warp_clock function with a single call.
That operation now takes 3 calls of settimeofday(2).
Although this common operation now takes three calls, the overall logic
for the set_system_clock() function was simplified.

libblkid: (xfs) external log: check for regular xfs on more sectors
The xfs external log probe only checks for regular xfs on sector zero,
but then checks for valid log record headers on all first 512 sectors.
This can incorrectly detect an xfs external log if a regular xfs (i.e.
with internal log) is shifted by up to 512 sectors; it may happen with
bcache and LVM1 for example, as the regular xfs is found later in disk.
This results in ambivalent filesystem detection, thus no UUID for udev.
Fix this problem by checking for regular xfs on all sectors considered
by the xfs external log probe.

libblkid: check for medium on CDMROMs probing
The commit 39f5af25982d8b0244000e92a9d0e0e6557d0e17 introduces
O_NONBLOCK to avoid the tray close on open(). The side effect is that
open() is successful when there is no medium.
This is usually no problem for standard tools because the next read()
will fail. Unfortunately, libblkid ignores I/O errors for (and only
for) CDROMs to support some crazy hybrid data+audio disks. The final
result is many I/O errors in system log when O_NONBLOCK is enabled.
This patch add CDROM_DRIVE_STATUS to stop probing when there is no
disk or when the tray is open.

doc: howto-man-page.txt: Use font macros instead of font escapes
Use font macros instead of font escapes (\f[BIPR]).
The escape '\c' ("connect to next input text")
is used to join the output of two macros without a space character.
This is similar to the '\' escape at the end of a line.
Font escapes make the text more difficult to read.
###
Changes based on:
Use a macro to change to the italic font,
instead of \fI [1], if possible.
The macros have the italic corrections,
but "\c" removes the "\/" part.
Or
add the italic corrections.

Change a HYPHEN-MINUS (code 0x55, 2D) to a minus (\-), if in front of a
1) name for an option
2) negative number to be printed.
###
Wrong distance between sentences or protect the indicator.
a) Separate the sentences and subordinate clauses;
each begins on a new line.
See man-pages(7) [package "manpages"] and "info groff".
Or
b) Adjust space between sentences (two spaces),
c) or protect the indicator by adding "\&" after it.
The "indicator" is an "end-of-sentence character" (.!?).
The amount of space between sentences in the output can then be
controlled with the ".ss" request.
Add a comma (,) after "e.g." and "i.e.", or use English words
(man-pages(7) [package "manpages"]).
Abbreviation points should be protected (usually with the
non-printing, zero width character '\&') from being interpreted as an
end of sentence, if they are not, and that independent of their current
place on the line.
This is important when typing, as one does not usually know in
advance when the editor jumps to a new line.
