lsfd: read the UNIX socket path including white spaces correctly
The original code uses '%s' scanf specifier to read lines in /proc/net/unix.
If white space is included in a path, lsfd could read only the first word of the path.
This commit fixes this bug.
Specifying the maximum length of path is suggested by Karel Zak <kzak@redhat.com>.

umount: don't ignore --quiet for non-root users
The command line option --quiet suppresses 'not mounted' error
messages. This does not work for non-root users because libmount does
not call umount(2) syscall, and in this case, the library returns
-EPERM.

add more concrete examples of how to use chrt(1)
I've come looking at this manpage with the simple "how do I make this
process use realtime scheduling?" question and couldn't find a
definite answer. Of course, RT is more complicated than "just make
this real time": there's various queues and scheduling classes, but I
think it's worth giving a good, simple example that should basically
work.
In particular, my use case was "my audio is stuttering, is this a
scheduling problem?" By picking the RR scheduler, we set a realtime
scheduling priority that's lower than kernel threads (e.g. migration
is FF/99, irq is FF/50) so that we go above existing processes, but
without kicking out more critical systems.
This, of course, is a matter of taste, and the settings here are a
little arbitrary. I send this patch in the hope that either those are
accepted as canon (which would surprise me) or that someone comes up
with a more canonical example.
The "reset" example also seems like a more critical addition to the
manual.
Finally, I change the name of the section from USAGE to the more
standard EXAMPLES, as per man-pages(7).
These checks are redundant as we already validated
* `dev_idx < bcs->nr_devices` in `probe_bcachefs()`
* `field + BYTES(field) < sb_end` in `probe_bcachefs_sb_fields()`
* `member_field_end(members, bcs->nr_devices - 1) == field + BYTES(field)`
right above.
