From: Yu Kuai <yukuai3@huawei.com> Changes in v8: - fix that another unrelated patch is merged into this patchset - update commit message for patch 5 - rebase on the top of another patch from me: [PATCH v3] md: fix duplicate filename for rdev Changes in v7: - add missing changes for md-cluster - rebase for the latest md-next branch Changes in v6: - remove first patch from v5, and use rcu_asign_pointer() directly from caller. - always use rcu_read_lock/unlock to protect mddev_set_timeout(). Changes in v5: - use rcu_dereference_protected() instead of rcu_access_pointer() where rcu_read_lock/unlock is not required. - add patch 4,5 to handle that bitmap timeout is set multiple times. Changes in v4: - remove patch 2 from v3 - fix sparse errors and warnings from v3, in order to do that, all access to md_thread need to be modified, patch 2-4 is splited to avoid a huge patch. Changes in v3: - remove patch 3 from v2 - use rcu instead of a new lock Changes in v2: - fix a compile error for md-cluster in patch 2 - replace spin_lock/unlock with spin_lock/unlock_irq in patch 5 - don't wake up inside the new lock in md wakeup_thread in patch 5 Yu Kuai (5): md: factor out a helper to wake up md_thread directly dm-raid: remove useless checking in raid_message() md/bitmap: always wake up md_thread in timeout_store md/bitmap: factor out a helper to set timeout md: protect md_thread with rcu drivers/md/dm-raid.c | 4 +- drivers/md/md-bitmap.c | 43 +++++++++++-------- drivers/md/md-cluster.c | 17 +++++--- drivers/md/md-multipath.c | 4 +- drivers/md/md.c | 88 +++++++++++++++++++++------------------ drivers/md/md.h | 8 ++-- drivers/md/raid1.c | 7 ++-- drivers/md/raid1.h | 2 +- drivers/md/raid10.c | 20 +++++---- drivers/md/raid10.h | 2 +- drivers/md/raid5-cache.c | 22 ++++++---- drivers/md/raid5.c | 15 +++---- drivers/md/raid5.h | 2 +- 13 files changed, 132 insertions(+), 102 deletions(-)
