[PATCH 0/2] scsi: revert two commits for avoiding host-wide host_busy counter for scsi_mq

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

 



Hi,

There is fundamental issue in commit 328728630d9f2bf1 (scsi: core: avoid
host-wide host_busy counter for scsi_mq) because SCSI's host busy counter
may not be same with counter of blk-mq's inflight tags, especially in case
of none io scheduler.

So please revert the two commits.

Ming Lei (2):
  Revert "scsi: core: fix scsi_host_queue_ready"
  Revert "scsi: core: avoid host-wide host_busy counter for scsi_mq"
