    dm raid: set MD_CHANGE_DEVS when rebuilding · 3aa3b2b2
    Jonathan E Brassow authored
    The 'rebuild' parameter is used to rebuild individual devices in an
    array (e.g. resynchronize a RAID1 device or recalculate a parity device
    in higher RAID).  The MD_CHANGE_DEVS flag must be set when this
    parameter is given in order to write out the superblocks and make the
    change take immediate effect.  The code that handles new devices in
    super_load already sets MD_CHANGE_DEVS and 'FirstUse'.  (The 'FirstUse'
    flag was being set as a special case for rebuilds in
    Add a condition for rebuilds in super_load to take care of both flags
    without the special case in 'super_init_validation'.
