lsfd: include linux/fcntl.h
asm/-headers are implementation details and not meant to be included
directly. Instead use the linux/ header which will always include the
correct asm/-headers.
flock: add support for using fcntl() with open file description locks
Currently, there is no way for shell scripts to safely access
resources protected by POSIX locking (fcntl with the F_SETLK/F_SETLKW
commands). For example, the glibc function lckpwdf(), used to
protect access to the /etc/shadow database, works by taking a
F_SETLKW on /etc/.pwd.lock .
Due to the odd semantics of POSIX locking (e.g. released when any file
descriptor associated to the inode is closed), we cannot usefully
directly expose the POSIX F_SETLK/F_SETLKW commands. However, linux
3.15 introduced F_OFD_SETLK[W], with semantics wrt. ownership and
release better matching those of flock(2), and crucially they do
conflict with locks obtained via F_SETLK[W]. With this, a shell script
can do
exec 4> /etc/.pwd.lock
flock --fcntl 4
<access/modify /etc/shadow ...>
flock --fcntl --unlock 4 # or just exit
without conflicting with passwd(1) or other utilities that
access/modify /etc/shadow.
No single-letter shorthand is defined for the option, because this is
somewhat low-level and the user really needs to know what he is doing.
Also, this leaves the door open for teaching --fcntl to accept an
optional argument: "ofd", the default, and "posix", should anyone find
a use for flock(1) taking a F_SETLK[W] lock.
tests: (lsns::ioctl_ns) record stdout/stderr for debugging the case
When the test case runs successfully, we expect the case test prints
nothing to stderr. If something is printed to stderr, it helps us
debug lsns command and the test case.

The function interpolate_missing_namespaces() reads data from /proc.

libmount: Fix access check for utab in context
The function mnt_has_regular_utab() properly detects that the utab is
not writable, but this is ignored by the high-level context API. As a
result, the library later attempts to update the file and ends up with
a warning in mount(8):
$ mkdir sys
$ unshare --map-root-user --mount
$ mount --rbind /sys sys
$ umount --lazy sys; echo $?
umount: /home/user/sys: filesystem was unmounted, but failed to update userspace mount table.
