-Subject: [PATCH 2/3] block: Revert v5.0 blk_mq_request_issue_directly()
- changes
-
-blk_mq_try_issue_directly() can return BLK_STS*_RESOURCE for requests that
-have been queued. If that happens when blk_mq_try_issue_directly() is called
-by the dm-mpath driver then dm-mpath will try to resubmit a request that is
-already queued and a kernel crash follows. Since it is nontrivial to fix
-blk_mq_request_issue_directly(), revert the blk_mq_request_issue_directly()
-changes that went into kernel v5.0.
-
-This patch reverts the following commits:
-* d6a51a97c0b2 ("blk-mq: replace and kill blk_mq_request_issue_directly") # v5.0.
-* 5b7a6f128aad ("blk-mq: issue directly with bypass 'false' in blk_mq_sched_insert_requests") # v5.0.
-* 7f556a44e61d ("blk-mq: refactor the code of issue request directly") # v5.0.
