Subject: [GIT PULL] namespace related changes for v4.12-rc1
Linus,
Please pull the for-linus branch from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git for-linus
HEAD: d66bb1607e2d8d384e53f3d93db5c18483c8c4f7 proc: Fix unbalanced hard link numbers
This is a set of small fixes that were mostly stumbled over during more
significant development. This proc fix and the fix to posix-timers
are the most significant of the lot.
There is a lot of good development going on but unfortunately it didn't
quite make the merge window.
Eric W. Biederman (7):
sysctl: Remove dead register_sysctl_root
posix-timers: Correct sanity check in posix_cpu_nsleep
ipc: Remove unused declaration of recompute_msgmni
ia64: Remove unused IA64_TASK_SIGHAND_OFFSET and IA64_SIGHAND_SIGLOCK_OFFSET
signal: Remove unused definition of sig_user_definied
rlimit: Properly call security_task_setrlimit
signal: Make kill_proc_info static
