[SCSI] bfa: fix possible IO double completion

2010-07-27T17:04:20+00:00

While processing the ioim in callback functions, the ioim is still in io_q.
During this time, if the itnim goes offline, the ioim is requeued from
itnim->io_q into itnim->delay_comp_q although the request is already completed.
This results in requeing the ioim into the callback queue if the ioim is not
freed by the time the ioim is requeued. This results in double completion of
the ioim. To fix this, whenever a response is received from firmware for an
ioim, deque it from io_q and enque to fcpim->comp_q. This will eliminate any
possibility of itnim picking any ioim for which the response is already
received.

[SCSI] bfa: fix the issue of not handling scsi_cmnd sg chaining case

2010-04-11T14:24:17+00:00

Currently the driver doesn't take into consideraion of possible sg chaining
when it walks through the sg list. This is fixed by using the sg_next()
which automatically handles the chaining case. Obosolete code is removed
as a result of this change.
