This is a note to let you know that I have just added a patch titled ext4: iterate over buffer heads correctly in move_extent_per_page() to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt26. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ---8<------------------------------------------------------------ From 1cd229323b0017e4f7c9418d405082b8f31b8d69 Mon Sep 17 00:00:00 2001 From: Eryu Guan <guaneryu@gmail.com> Date: Sun, 21 Feb 2016 18:38:44 -0500 Subject: ext4: iterate over buffer heads correctly in move_extent_per_page() commit 6ffe77bad545f4a7c8edd2a4ee797ccfcd894ab4 upstream. In commit bcff24887d00 ("ext4: don't read blocks from disk after extents being swapped") bh is not updated correctly in the for loop and wrong data has been written to disk. generic/324 catches this on sub-page block size ext4.
