Jonathan Brassow 47525e59e4 DM RAID: Set recovery flags on resume ... Properly initialize MD recovery flags when resuming device-mapper devices. When a device-mapper device is suspended, all I/O must stop. This is done by calling 'md_stop_writes' and 'mddev_suspend'. These calls in-turn manipulate the recovery flags - including setting 'MD_RECOVERY_FROZEN'. The DM device may have been suspended while recovery was not yet complete, so the process needs to pick-up where it left off. Since 'mddev_resume' does not unset 'MD_RECOVERY_FROZEN' and set 'MD_RECOVERY_NEEDED', we must do it ourselves. 'MD_RECOVERY_NEEDED' can safely be set in 'mddev_resume', but 'MD_RECOVERY_FROZEN' must be set outside of 'mddev_resume' due to how MD handles RAID reshaping. (e.g. It is possible for a user to delay reshaping a RAID5->RAID6 by purposefully setting 'MD_RECOVERY_FROZEN'. Clearing it in 'mddev_resume' would override the desired behavior.) Because 'mddev_resume' already unconditionally calls 'md_wakeup_thread(mddev->thread)' there is no need to make this call from 'raid_resume' since it calls 'mddev_resume'. Also clean up where level_store calls mddev_resume() - it current duplicates some of the funcitons of that call. - NB Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>		2012-05-22 13:55:29 +10:00
