Subject: [PATCHv5 00/11] scsi: remove legacy cmd_list implementation
Date: Wed, 20 Nov 2019 11:31:03 +0100 [thread overview]
Message-ID: <20191120103114.24723-1-hare@suse.de> (raw)
Hi all,
with the switch to blk-mq we have an efficient way of looking up
outstanding commands via blk_mq_rq_busy_iter().
In this patchset the dpt_i2o and aacraid drivers are switched over
to using that function, and the now obsolete cmd_list implemantation
in the SCSI midlayer is removed.
As usual, comments and reviews are welcome.
Changes to v1:
- Fixup kbuild warning
Changes to v2:
- Add scsi_host_busy_iter()
- Include reviews from Christoph
Changes to v3:
- Include reviews from Christoph
- Add midlayer helper to terminate outstanding commands
- Split off aacraid modifcations into several patches
Changes to v4:
- Include reviews from Bart
- Add new midlayer helper scsi_host_quiesce()/scsi_host_resume()
- Improve comments
Hannes Reinecke (11):
dpt_i2o: rename adpt_i2o_to_scsi() to adpt_i2o_scsi_complete()
scsi: add scsi_host_flush_commands() helper
dpt_i2o: use scsi_host_flush_commands() to abort outstanding commands
aacraid: Do not wait for outstanding write commands on
synchronize_cache
aacraid: use midlayer helper to terminate outstanding commands
aacraid: replace aac_flush_ios() with midlayer helper
scsi: add scsi_host_quiesce()/scsi_host_resume() helper
aacraid: use scsi_host_quiesce() to wait for I/O to complete
scsi: add scsi_host_busy_iter()
aacraid: use scsi_host_busy_iter() in get_num_of_incomplete_fibs()
scsi: Remove cmd_list functionality
