This is a note to let you know that I have just added a patch titled writeback: initialize inode members that track writeback history to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt5. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From 84072fc06e2628004e00946d73a0bd02b15b715d Mon Sep 17 00:00:00 2001 From: Tahsin Erdogan <tahsin@google.com> Date: Tue, 16 Feb 2016 13:34:39 -0800 Subject: writeback: initialize inode members that track writeback history commit 3d65ae4634ed8350aee98a4e6f4e41fe40c7d282 upstream. inode struct members that track cgroup writeback information should be reinitialized when inode gets allocated from kmem_cache. Otherwise, their values remain and get used by the new inode.
