Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace fix from Eric Biederman:
"This has a single brown bag fix.
The possible deadlock with dec_pid_namespaces that I had thought was
fixed earlier turned out only to have been moved. So instead of being
cleaver this change takes ucounts_lock with irqs disabled. So
dec_ucount can be used from any context without fear of deadlock.
The items accounted for dec_ucount and inc_ucount are all
comparatively heavy weight objects so I don't exepct this will have
any measurable performance impact"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
userns: Make ucounts lock irq-safe
