The patch titled
fuse: fix reserved request wake up
has been removed from the -mm tree. Its filename was
fuse-fix-reserved-request-wake-up.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: fuse: fix reserved request wake up
From: Miklos Szeredi <mszeredi@xxxxxxx>
Use wake_up_all instead of wake_up in put_reserved_req(), otherwise it is
possible that the right task is not woken up.
Also create a separate reserved_req_waitq in addition to the blocked_waitq,
since they fulfill totally separate functions.
