Subject: [PATCH 0/3] hisi_sas: some CQ processing fixes
Date: Tue, 3 Jan 2017 20:24:47 +0800 [thread overview]
Message-ID: <1483446290-185084-1-git-send-email-john.garry@huawei.com> (raw)
This patchset fixes some issues related to servicing of the
completion queue interrupt.
The major fix is that sensitive hisi_hba structures need to be
locked when free'ing a slot.
Another modification is that the v2 hw completion queue irq is
now serviced with a tasklet, as too much work was being done in
the ISR.
