[PATCHv8 00/13] scsi: remove legacy cmd_list implementation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

Changes to v5:
- Add reviews from Balsundar P.
- Rename scsi_host_flush_commands()
- Replace patch using scsi_host_quiesce() by using busy iterator

Changes to v6:
- Add reviews from Balsundar P.

Changes to v7:
- Add reviews from Christoph
