fuse: add missing FR_FORCE

commit 2e38bea99a80eab408adee27f873a188d57b76cb upstream. fuse_file_put() was missing the "force" flag for the RELEASE request when sending synchronously (fuseblk). If this flag is not set, then a sync request may be interrupted before it is dequeued by the userspace filesystem. In this case the OPEN won't be balanced with a RELEASE. [js] force is a variable, not a bit Signed-off-by: Miklos Szeredi <[email protected]> Fixes: 5a18ec1 ("fuse: fix hang of single threaded fuseblk filesystem") Signed-off-by: Jiri Slaby <[email protected]> Signed-off-by: Willy Tarreau <[email protected]>
