This is a note to let you know that I have just added a patch titled ext4: fix bigalloc regression to the linux-3.11.y-queue branch of the 3.11.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-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 7c2fba08d97d140bc9be5cfadefe63f674226fe3 Mon Sep 17 00:00:00 2001 From: Eric Whitney <enwlinux@gmail.com> Date: Mon, 6 Jan 2014 14:00:23 -0500 Subject: ext4: fix bigalloc regression commit d0abafac8c9162f39c4f6b2f8141b772a09b3770 upstream. Commit f5a44db5d2 introduced a regression on filesystems created with the bigalloc feature (cluster size > blocksize). It causes xfstests generic/006 and /013 to fail with an unexpected JBD2 failure and transaction abort that leaves the test file system in a read only state. Other xfstests run on bigalloc file systems are likely to fail as well. The cause is the accidental use of a cluster mask where a cluster offset was needed in ext4_ext_map_blocks().
