md: Fix missing release of 'active_io' for flush
commit 855678ed8534518e2b428bcbcec695de9ba248e8 upstream.
submit_flushes atomic_set(&mddev->flush_pending, 1); rdev_for_each_rcu(rdev, mddev) atomic_inc(&mddev->flush_pending); bi->bi_end_io = md_end_flush submit_bio(bi); /* flush io is done first */ md_end_flush if (atomic_dec_and_test(&mddev->flush_pending)) percpu_ref_put(&mddev->active_io) -> active_io is not released
if (atomic_dec_and_test(&mddev->flush_pending)) -> missing release of active_io
For consequence, mddev_suspend() will wait for 'active_io' to be zero forever.
Fix this problem by releasing 'active_io' in submit_flushes() if 'flush_pending' is decreased to zero.

md: bypass block throttle for superblock update
[ Upstream commit d6e035aad6c09991da1c667fb83419329a3baed8 ]
commit 5e2cf333b7bd ("md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d") introduced a hung bug and will be reverted in next patch, since the issue that commit is fixing is due to md superblock write is throttled by wbt, to fix it, we can have superblock write bypass block layer throttle.

md: Whenassemble the array, consult the superblock of the freshest device
[ Upstream commit dc1cc22ed58f11d58d8553c5ec5f11cbfc3e3039 ]
Upon assembling the array, both kernel and mdadm allow the devices to have event counter difference of 1, and still consider them as up-to-date. However, a device whose event count is behind by 1, may in fact not be up-to-date, and array resync with such a device may cause data corruption. To avoid this, consult the superblock of the freshest device about the status of a device, whose event counter is behind by 1.

md: synchronize flush io with array reconfiguration
[ Upstream commit fa2bbff7b0b4e211fec5e5686ef96350690597b5 ]
Currently rcu is used to protect iterating rdev from submit_flushes():
submit_flushes remove_and_add_spares synchronize_rcu pers->hot_remove_disk() rcu_read_lock() rdev_for_each_rcu if (rdev->raid_disk >= 0) rdev->radi_disk = -1; atomic_inc(&rdev->nr_pending) rcu_read_unlock() bi = bio_alloc_bioset() bi->bi_end_io = md_end_flush bi->private = rdev submit_bio // issue io for removed rdev
Fix this problem by grabbing 'acive_io' before iterating rdev, make sure that remove_and_add_spares() won't concurrent with submit_flushes().

md: don't leave 'MD_RECOVERY_FROZEN' in error path of md_set_readonly()

md: don't leave 'MD_RECOVERY_FROZEN' in error path of md_set_readonly()
[ Upstream commit c9f7cb5b2bc968adcdc686c197ed108f47fd8eb0 ]
If md_set_readonly() failed, the array could still be read-write, however 'MD_RECOVERY_FROZEN' could still be set, which leave the array in an abnormal state that sync or recovery can't continue anymore. Hence make sure the flag is cleared after md_set_readonly() returns.

md: fix bi_status reporting in md_end_clone_io
commit 45b478951b2ba5aea70b2850c49c1aa83aedd0d2 upstream.
md_end_clone_io() may overwrite error status in orig_bio->bi_status with BLK_STS_OK. This could happen when orig_bio has BIO_CHAIN (split by md_submit_bio => bio_split_to_limits, for example). As a result, upper layer may miss error reported from md (or the device) and consider the failed IO was successful.
Fix this by only update orig_bio->bi_status when current bio reports error and orig_bio is BLK_STS_OK. This is the same behavior as __bio_chain_endio().
