Subject: md: 'sync_action' in sysfs returns wrong value for readonly arrays
From: NeilBrown <neilb@xxxxxxx>
When an array is started read-only, MD_RECOVERY_NEEDED can be set but no
recovery will be running. This causes 'sync_action' to report the wrong
value.
We could remove the test for MD_RECOVERY_NEEDED, but doing so would leave a
small gap after requesting a sync action, where 'sync_action' would still
report the old value.
So make sure that for a read-only array, 'sync_action' always returns 'idle'.
