Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace fixes from Eric Biederman:
"This tree includes two bug fixes for problems Oleg spotted on his
review of the recent pid namespace work. A small fix to not enable
bottom halves with irqs disabled, and a trivial build fix for f2fs
with user namespaces enabled."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
f2fs: Don't assign e_id in f2fs_acl_from_disk
proc: Allow proc_free_inum to be called from any context
pidns: Stop pid allocation when init dies
pidns: Outlaw thread creation after unshare(CLONE_NEWPID)
