SCSI host lock push-down

2010-11-16T21:33:23+00:00

Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.

The patch below presents a simple SCSI host lock push-down as an
equivalent transformation.  No locking or other behavior should change
with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,
	struct Scsi_Host *
and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.

[SCSI] bfa: fix comments for c files

2010-10-25T21:28:09+00:00

This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com)
regarding comment blocks that begining with "/**". bfa driver comments
currently do not follow kernel-doc convention, we hence replace all
/** with /* and **/ with */.

[SCSI] bfa: remove os wrapper and unused functions

2010-10-25T21:15:58+00:00

This patch removes os wrapper and unused functions.
bfa_os_assign(), bfa_os_memset(), bfa_os_memcpy(), bfa_os_udelay()
bfa_os_vsprintf(), bfa_os_snprintf(), and bfa_os_get_clock() are replaced with
direct assignment or native linux functions. Some unused functions related to VF
(Vitual fabric) are also removed.
