Subject: two ahci fixes from code inspection
Date: Thu, 11 Aug 2016 07:26:00 -0700 [thread overview]
Message-ID: <1470925562-28914-1-git-send-email-hch@lst.de> (raw)
Hi Tejun,
below are two things in ahci I found while converting the driver
to the new MSI / MSI-X vector allocator.
The first one looks like an obvious bug to me if we every have
these stray ports in a per-port IRQ vector setup.
The others one is more elaborate, but I think the per-port locking
is something we should do for the per-port MSI-X case just like for
the per-port MSI case.
