This is a note to let you know that I have just added a patch titled md/raid10: Fix memory leak when raid10 reshape completes. 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. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 7ffce3c577cc8f409606000295160ef6a1954361 Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.de> Date: Mon, 18 Aug 2014 13:59:50 +1000 Subject: md/raid10: Fix memory leak when raid10 reshape completes. commit b39685526f46976bcd13aa08c82480092befa46c upstream. When a raid10 commences a resync/recovery/reshape it allocates some buffer space. When a resync/recovery completes the buffer space is freed. But not when the reshape completes. This can result in a small memory leak. There is a subtle side-effect of this bug. When a RAID10 is reshaped to a larger array (more devices), the reshape is immediately followed by a "resync" of the new space. This "resync" will use the buffer space which was allocated for "reshape". This can cause problems including a "BUG" in the SCSI layer. So this is suitable for -stable.
