Andrey, It is helpful to send your review to the patch author. I've added Konstantin to the Cc list, as well as Raghava (who introduced the regression addressed by Konstantin's patch). If I'm not mistaken, your review misunderstands the patch description. FWIW, Konstantin's patch might have been easier to follow if it was a simple 'git revert'.

Hi Finn, Andrey, Finn, thank you for putting me back to the thread, appreciated. And i agree with you, may be git revert followed by independent patch which removes Series-9 mentions is easier to read, so sending the second version - in that way. Andrey, please take a look at the new version patches, hope it's easier to understand. And talking about the helper: i thought about leaving it, but we have several places which check for Series 7 and 8 only and several places which check for Series 6,7,8, so either - we need 2 helpers - we have a helper to check for Series 7,8 only and in some places will have a check for Series 6 + helper - introduce the helper with parameter Honestly i don't like any of variants above, so just left the code without helper, not that many checks and easier to read the code IMHO. Thank you! -- Best regards, Konstantin Khorenko, Virtuozzo Linux Kernel Team

This partially reverts ms commit 395e5df79a95 ("scsi: aacraid: Remove reference to Series-9") The patch above not only drops Series-9 cards checks but also changes logic for Series-6 controllers which leads to controller hangs/resets under high io load. So revert to original arc ctrl checks for Series-6 controllers. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777586 https://bugzilla.redhat.com/show_bug.cgi?id=1724077 https://jira.sw.ru/browse/PSBM-95736 Fixes: 395e5df79a95 ("scsi: aacraid: Remove reference to Series-9") Cc: stable@vger.kernel.org Signed-off-by: Konstantin Khorenko <khorenko@virtuozzo.com> --- drivers/scsi/aacraid/aacraid.h | 11 ----------- drivers/scsi/aacraid/comminit.c | 14 ++++++++++---- drivers/scsi/aacraid/commsup.c | 4 +++- drivers/scsi/aacraid/linit.c | 7 +++++-- 4 files changed, 18 insertions(+), 18 deletions(-)
