This is a note to let you know that I have just added a patch titled jbd2: fix infinite loop when recovering corrupt journal blocks to the linux-3.13.y-queue branch of the 3.13.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-3.13.y-queue This patch is scheduled to be released in version 3.13.11.8.

Wong" <darrick.wong@oracle.com> Date: Wed, 27 Aug 2014 18:40:05 -0400 Subject: jbd2: fix infinite loop when recovering corrupt journal blocks commit 022eaa7517017efe4f6538750c2b59a804dc7df7 upstream. When recovering the journal, don't fall into an infinite loop if we encounter a corrupt journal block. Instead, just skip the block and return an error, which fails the mount and thus forces the user to run a full filesystem fsck. Signed-off-by: Darrick J.
