The patch titled

has been removed from the -mm tree. Its filename was
jffs2-remove-wait-queue-after-schedule.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Li Zefan <lizefan@xxxxxxxxxx>
Subject: jffs2: remove wait queue after schedule()
@wait is a local variable, so if we don't remove it from the wait queue
list, later wake_up() may end up accessing invalid memory.
This was spotted by eyes.
