Subject: [PATCH 0/2 v2] Make blk_cleanup_queue() finish after request_fn
Date: Sun, 23 Sep 2012 18:16:09 +0200 [thread overview]
Message-ID: <505F35C9.6070509@acm.org> (raw)
Request processing functions like scsi_request_fn() that unlock the
queue lock internally may cause blk_cleanup_queue() to finish while
the request_fn is in progress. This two-patch series makes sure that
blk_cleanup_queue() can't finish before all active request_fn calls
have finished.
Changes compared to v1:
- Included a patch to rename QUEUE_FLAG_DEAD.
- Refined the descriptions of the __blk_run_queue_uncond() and
blk_cleanup_queue() functions.
