[PATCH] fuse: fix bug in aborted fuse_release_end()
There's a rather theoretical case of the BUG triggering in fuse_reset_request(): - iget() fails because of OOM after a successful CREATE_OPEN request - during IO on the resulting RELEASE request the connection is aborted Fix and add warning to fuse_reset_request().
