Miklos Szeredi 9fd11e2de7 fuse: lock inode unconditionally in fuse_fallocate() ... commit 44361e8cf9ddb23f17bdcc40ca944abf32e83e79 upstream. file_modified() must be called with inode lock held. fuse_fallocate() didn't lock the inode in case of just FALLOC_KEEP_SIZE flags value, which resulted in a kernel Warning in notify_change(). Lock the inode unconditionally, like all other fallocate implementations do.
