Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse fixes from Miklos Szeredi: "This adds ctime update in the new cached writeback mode and also fixes/simplifies the mtime update handling. Support for rename flags (aka renameat2) is also added to the userspace API" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: fuse: add renameat2 support fuse: clear MS_I_VERSION fuse: clear FUSE_I_CTIME_DIRTY flag on setattr fuse: trust kernel i_ctime only fuse: remove .update_time fuse: allow ctime flushing to userspace fuse: fuse: add time_gran to INIT_OUT fuse: add .write_inode fuse: clean up fsync fuse: fuse: fallocate: use file_update_time() fuse: update mtime on open(O_TRUNC) in atomic_o_trunc mode fuse: update mtime on truncate(2) fuse: do not use uninitialized i_mode fuse: fix mtime update error in fsync fuse: check fallocate mode fuse: add __exit to fuse_ctl_cleanup
