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
