X-Git-Tag: omap-for-v3.17/fixes-against-rc2~39^2~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b39685526f46976bcd13aa08c82480092befa46c;p=pandora-kernel.git md/raid10: Fix memory leak when raid10 reshape completes. 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.
