6.10-stable review patch. If anyone has any objections, please let me know.

commit 2f3d8ff457982f4055fe8f7bf19d3821ba22c376 upstream.
This may be a typo. The comment has said shared locks are not allowed when this bit is set. If using shared lock, the wait in `fuse_file_cached_io_open` may be forever.
