[PATCH 4.9 20/83] fuse: fix blocked_waitq wakeup

2018-11-19 Thread Greg Kroah-Hartman
4.9-stable review patch. If anyone has any objections, please let me know. -- From: Miklos Szeredi commit 908a572b80f6e9577b45e81b3dfe2e22111286b8 upstream. Using waitqueue_active() is racy. Make sure we issue a wake_up() unconditionally after storing into fc->blocked.
