This is a note to let you know that I have just added a patch titled jffs2: remove from wait queue after schedule() to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.22. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 8f5a0e2c7317a943f2a8b57c89f45f8decb1d77e Mon Sep 17 00:00:00 2001 From: Li Zefan <lizefan@huawei.com> Date: Wed, 12 Feb 2014 12:44:57 -0800 Subject: jffs2: remove from wait queue after schedule() commit 3ead9578443b66ddb3d50ed4f53af8a0c0298ec5 upstream. @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.
