Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse updates from Miklos Szeredi: "This fixes error propagation from writeback to fsync/close for writeback cache mode as well as adding a missing capability flag to the INIT message. The rest are cleanups. (The commits are recent but all the code actually sat in -next for a while now. The recommits are due to conflict avoidance and the addition of Cc: stable@...)" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: fuse: use filemap_check_errors() mm: export filemap_check_errors() to modules fuse: fix wrong assignment of ->flags in fuse_send_init() fuse: fuse_flush must check mapping->flags for errors fuse: fsync() did not return IO errors fuse: don't mess with blocking signals new helper: wait_event_killable_exclusive() fuse: improve aio directIO write performance for size extending writes
