From v4.4, linux kernel starts to support direct I/O and
AIO to backing file for loop driver, so allow losetup to
enable the feature by using LOOP_SET_DIRECT_IO ioctl cmd.

The libmount provides way how to deal with parsing errors in fstab --
on error callback function is executed and according to the return
libmount manipulate with the malformed line, possible are three
states:
1/ fatal error; all file ignored (callback rc < 0)
2/ recoverable error; malformed line ignored (callback rc > 0)
3/ ignore the error (callback rc == 0)
The 2/ is the default if no callback specified.
Unfortunately our utils uses 3/. The correct way is to use 2/.

We care about /proc/device-tree/compatible content...
The patch also removes unnecessary path_exist(), it seems good enough
to call open() rather than access() + open().

FALLOC_FL_KEEP_SIZE flag is generic and used in many situations,
"-n" in the error message does not make sense.

Now it's necessary t use two mount(8) calls to create a read-only
mount:
mount /foo /bar -o bind
mount /bar -o remount,ro,bind
This patch allows to specify "bind,ro" and the remount is done
automatically by libmount by additional mount(2) syscall. It's not
atomic of course.

* 'colcrt' of git://github.com/kerolasa/lelux-utiliteetit:
tests: add colcrt regression tests
colcrt: allocate enough space for data moves [afl & asan]
colcrt: avoid writing beyond array bound [afl & asan]
colcrt: use #define in place of magic constants
misc: fix redundant assignment and reassignments before use [cppcheck]
tools: stop checkmans.sh validating libtool builds
* 'patch-1' of https://github.com/borutmrak/util-linux:
mount.8: also note diratime does not override noatime.
mount.8: Clarify relation between noatime and nodiratime
According to https://lwn.net/Articles/245002/ and checking Linus' git master fs/inode.c it's obvious nodiratime is redundant when mounting with noatime. Clarify that in the man page.
This patch allows to use things like:
# lsipc -m --id 47611910 -o COMMAND,SIZE,KEY --json
or
# lsipc -m --id 47611910 -o SIZE --bytes --noheadings --raw
to get just one value for the resource.
