Hey, We hit another bug on my recent batching patch. In this case the bug has never been hit with the current md/md-next branch but some other patches we were working on changed the timing such that we hit this bug. It is theoretically possible to hit in the md/md-next batch so this patchset contains a fix. The fix is the last commit. The first four commits are some basic refactoring that makes the final commit a bit easier. A git repo is here and is based on current md/md-next (7a6f9e9cf1): https://github.com/sbates130272/linux-p2pmem raid5_batch_quiesce Thanks, Logan -- Logan Gunthorpe (5): md/raid5: Refactor raid5_get_active_stripe() md/raid5: Make is_inactive_blocked() helper md/raid5: Drop unnecessary call to r5c_check_stripe_cache_usage() md/raid5: Move stripe_request_ctx up md/raid5: Ensure batch_last is released before sleeping for quiesce drivers/md/raid5.c | 162 ++++++++++++++++++++++++++++----------------- drivers/md/raid5.h | 2 +- 2 files changed, 101 insertions(+), 63 deletions(-) base-commit: 7a6f9e9cf1befa0a1578501966d3c9b0cae46727 -- 2.30.2
