X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a4a3d26d8757a30ae21724d8b0d79e00e113c38d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git md: set MD_RECOVERY_RECOVER when starting a degraded array. This ensures that 'sync_action' will show 'recover' immediately the array is started. If there is no spare the status will change to 'idle' once that is detected. Clear MD_RECOVERY_RECOVER for a read-only array to ensure this change happens. This allows scripts which monitor status not to get confused - particularly my test scripts.
