Comment 0 for bug 1689980

Hello team,
It seems Microsemi team has requested to backport few AACRAID driver patches for Power 9 platform for 17.04 and 16.04.3 kernel.

Hi Narinder,

We have submitted a handful of critical fixes for the AACRAID driver on to the kernel.org, targeting 4.11. These patches are bug fixes and our customer IBM is expecting these patches to go into the 16.04.3 release, for to use with the Power9 platforms.

Can you please let me know if these patches will be backported by your kernel team on to the upcoming 16.04.3? Do you also have a schedule in place for 16.04.3 release?

Thanks,
Gana

Below are the patch details.

Subject: [PATCH V2 00/19] aacraid: Patchset with reset rework and misc fixes

This patchset primarily focuses on tweaking and hardening the controller reset support for both ARC and HBA1000 devices. Now the driver can only reset the controller thru eh reset. Included a srb memory fix and pci dma allocation fix.

Changes in V2:
 - Corrected heading and description for srb memory patch and removed stray
   comment.
 - Removed incorrect up function call and cleared fib wait flag after call
   to down interruptible in the ioctl return on ctrl reset patch.

   finding the above issues in the above 2 patches.
