9c291f2cc0 taskset: fix for PID longer than 12 chars
Should we validate that PID is a number for "taskset -ap PID"?
We don't actually need it, and pathological input like
"../../DIR_WITH_LOTS_OF_PIDS" can only cause "taskset"ing
of many pids. Which is something user can do anyway.

6cfec7dd02 mount: Surround syslog.h with the config check
This lets bb mount build for limited targets without syslog.h,
as long as the parts using it like NFS are disabled.

56ee576507 mount: fix incorrect "success" exitcode if loop device setup fails
When mounting, in parallel, multiple loop devices (squashfs for the
submitter's case), the following behavior can be observed:

stat64(/path/to/image, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0
openat(AT_FDCWD, /path/to/image, O_RDWR|O_LARGEFILE) = 3
openat(AT_FDCWD, /dev/loop-control, O_RDWR|O_LARGEFILE|O_CLOEXEC) = 4
ioctl(4, LOOP_CTL_GET_FREE)             = 12
close(4)                                = 0
openat(AT_FDCWD, /dev/loop12, O_RDWR|O_LARGEFILE) = 4
ioctl(4, LOOP_GET_STATUS64, {lo_offset=0, lo_number=12, lo_flags=LO_FLAGS_AUTOCLEAR, lo_file_name=/path/to/image, ...}) = 0
close(4)                                = 0
close(3)                                = 0
write(2, "mount: can't setup loop device\n", 31mount: can't setup loop device
) = 31
exit_group(0)                           = ?
+++ exited with 0 +++

The ioctl LOOP_CTL_GET_FREE has resulted in the same result for
a competing mount process. The subsequent ioctl LOOP_GET_STATUS64
fails, having succeeded for the competing mount process.

If logging to stderr and/or syslog the -v option can be given one or
more times to increase the log verbosity. If mdev is used as hotplug
helper the log level is fixed set to 2 if mdev.log is found an appended
because there is no possiblity to pass arguments to the hotplug helper.

e9003caf6d mdev: add syslog logging mode
If mdev is run as daemon it should be possible to forward the debug
messages to syslog. This feature might be useful if mdev is run with -s
during boot too. OTOH it makes no sense for the daemon to log to
mdev.log. This can be handled by a syslog daemon way better. If the
daemon stays in the foreground due to -f, the messages are still written
to stderr as before.

If the netlink read() failed with ENOBUFS we know that we have missed at
least one message due to a socket receive buffer overrun. The only way
how to recover is to drop the old socket, open a fresh one and make a
cold-plug scan of the current system state.

3cd55d49a2 mdev: increase netlink buffer sizes
The socket receive buffer turned out to be too small for real world
systems. Use the same size as udevd to be on the safe side. As this is
just a limit and the memory is not allocated by the kernel until really
needed there is actually no memory wasted.

89f063b900 chrt: support for musl C library
musl "implements" several sched_xxx() functions by returning ENOSYS. As
an alternative, either pthread_(g|s)etschedparam() or direct syscalls
can be used.
