Merge branch 'fsnotify' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull fsnotify updates from Jan Kara:
"The branch contains mainly a rework of fsnotify infrastructure fixing
a shortcoming that we have waited for response to fanotify permission
events with SRCU read lock held and when the process consuming events
was slow to respond the kernel has stalled.
It also contains several cleanups of unnecessary indirections in
fsnotify framework and a bugfix from Amir fixing leakage of kernel
internal errno to userspace"
