struct fc_bsg_buffer is just a clone of struct bsg_buffer from bsg-lib,
so use this one instead.

Don't use fc_bsg_job::request and fc_bsg_job::reply directly, but use
helper variables bsg_request and bsg_reply. This will be helpfull when
transitioning to bsg-lib.

Don't use fc_bsg_job::request and fc_bsg_job::reply directly, but use
helper variables bsg_request and bsg_reply. This will be helpfull when
transitioning to bsg-lib.

Export fc_bsg_jobdone so drivers can use it directly instead of doing
the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs.
That way we can also unify the interfaces of fc_bsg_jobdone and bsg_job_done.
As we've converted all LLDDs over to use fc_bsg_jobdone() directly,
we can remove the function pointer from struct fc_bsg_job as well.

Export fc_bsg_jobdone so drivers can use it directly instead of doing
the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs.
That way we can also unify the interfaces of fc_bsg_jobdone and bsg_job_done.
As we've converted all LLDDs over to use fc_bsg_jobdone() directly,
we can remove the function pointer from struct fc_bsg_job as well.

Provide fc_bsg_to_shost() helper that will become handy when we're moving from
struct fc_bsg_job to a plain struct bsg_job. Also use this little helper in
the LLDDs.

Provide fc_bsg_to_rport() helper that will become handy when we're moving
from struct fc_bsg_job to a plain struct bsg_job. Also move all LLDDs to use
the new helper.

Provide fc_bsg_to_rport() helper that will become handy when we're moving
from struct fc_bsg_job to a plain struct bsg_job. Also move all LLDDs to use
the new helper.

Don't set FC_RQST_STATE_DONE before calling fc_bsg_jobdone() as
fc_bsg_jobdone() calls blk_complete_requeust() which raises a soft-IRQ that
ends up in fc_bsg_sofirq_done() and fc_bsg_softirq_done() sets the
FC_RQST_STATE_DONE flag.

Implement kref backed reference counting instead of rolling our own. This
elimnates the need of the following fields in 'struct fc_bsg_job':
* ref_cnt
* state_flags
* job_lock
bringing us close to unification of 'struct fc_bsg_job' and 'struct bsg_job'.

Implement kref backed reference counting instead of rolling our own. This
elimnates the need of the following fields in 'struct fc_bsg_job':
* ref_cnt
* state_flags
* job_lock
bringing us close to unification of 'struct fc_bsg_job' and 'struct bsg_job'.

Add reference counting to 'struct bsg_job' so we can implement a reuqest
timeout handler for bsg_jobs, which is needed for Fibre Channel.

fc_destroy_bsgjob() and bsg_destroy_job() are now 1:1 copies, so use the

once CONFOG_SCSI_FC_ATTRS is active.

Now that all conversions are done, move the FibreChannel bsg code over to the

This patch is derived from work done by Mike Christie in 2011 [1] but only the
iscsi parts got merged back then.

* [PATCH v4 14/15] scsi: fc: move FC transport's bsg code to bsg-lib
@ 2016-11-17 9:31 ` Johannes Thumshirn

Cc: Hannes Reinecke, Christoph Hellwig, Johannes Thumshirn,
open list:SCSI SUBSYSTEM, open list
Now that all conversions are done, move the FibreChannel bsg code over to the
bsg library.
This patch is derived from work done by Mike Christie in 2011 [1] but only the
iscsi parts got merged back then.

Unexport bsg_softirq_done() again, we don't need it outside of bsg-lib.c
anymore now that scsi_transport_fc is a pure bsg-lib client.

* [PATCH RESEND v4 00/15] Convert FibreChannel bsg code to use bsg-lib

This series converts the current bsg usage in the FibreChannel drivers over
to use bsg-lib. SAS will follow once FC is in a good enough shape.
I did take some inspiration from a similar patchset from Mike Christie
dating back to 2011 but it's not a 1:1 copy. Patch 15/16 is heavily based
on his series and attribution is given to him in the commit message.
It is currently regression tested on FCoE and lpfc using the 'fcns',
'fcrls' and 'fcping' (see my FC_BSG_RPT_ELS patch for fcping) utilities and
zfcp_show/zfcp_ping on s390x.
The idea for this change arose when discussing racy sysfs handling the FC
bsg code with Christoph and is a next step in moving all bsg clients to
bsg-lib to eventually clean up the in kernel bsg API.
Changes to v1:
* Reduce the number of individual patches (44 -> 16)
* Fix s390 build failure (forgotten to kill fc_bsg_job from zfcp_ext.h)
* Fix build failure on configs without CONFIG_BLK_DEV_BSGLIB
* Make bsg_job_get() call kref_get_unless_zero() and use it in scsi_transport_fc.c
Changes to v2:
* Add Hannes' Reviewd-by tags
* Address Hannes' comment about kref handling in 8/16
* Move CONFIG_BLK_DEV_BSGLIB dependency to patch 12/16 as per 0day results
Changes to v3:
* Rebase on mkp/4.10/scsi-queue (and fixup the new lpfc bsg function)
* Move checks for request and reply len before accessing them (hopefully fixes zfcp)
* Added Tyrel's Acked-bys
* Added Christoph's Reviewed-bys
* Squashed bsg_job_done patches as requested by Christoph
* Fixed the hopefully last bisection breaking point
* Fixed kernel panic on s390 with patch 2/15
* Fixed kernel panic on s390 with patch 5/15
* Fixed zfcp_show output on s390 with patch 4/15
Johannes Thumshirn (15):
scsi: Get rid of struct fc_bsg_buffer
scsi: don't use fc_bsg_job::request and fc_bsg_job::reply directly
scsi: fc: Export fc_bsg_jobdone and use it in FC drivers

fc_destroy_bsgjob() and bsg_destroy_job() are now 1:1 copies, so use the
later. As bsg_destroy_job() comes from bsg-lib we need to select it in Kconfig
once CONFOG_SCSI_FC_ATTRS is active.
