Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse update from Miklos Szeredi:
"The first part makes sure we don't hold up umount with pending async
requests. In addition to being a cleanup, this is a small behavioral
change (for the better) and unlikely to break anything.
The second part prepares for a cleanup of the fuse device I/O code by
adding a helper for simple request submission, with some savings in
line numbers already realized"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse:
fuse: use file_inode() in fuse_file_fallocate()
fuse: introduce fuse_simple_request() helper
fuse: reduce max out args
fuse: hold inode instead of path after release
fuse: flush requests on umount
fuse: don't wake up reserved req in fuse_conn_kill()
