Greg, Please queue eab6ee1ce3c4. -- Martin K. Petersen Oracle Linux Engineering commit eab6ee1ce3c4678224d70338134f7a02005768cb Author: Martin K. Petersen <[email protected]> Date: Tue May 19 19:44:17 2015 -0400 libata: Fix regression when the NCQ Send and Receive log page is absent Commit 5d3abf8ff67f ("libata: Fall back to unqueued READ LOG EXT if the DMA variant fails") allowed us to fall back to the unqueued READ LOG variant if the queued version failed. However, if the device did not support the page at all we would end up looping due to a merge snafu. Ensure we only take the fallback path once. Signed-off-by: Martin K.
