[PATCH] md: make sure raid5/raid6 resync uses correct 'max_sectors'
The default resync_max_sector is set to "mddev->size << 1". If the raid-personality-module updates mddev->size, it must update resync_max_sectors too. Signed-off-by: Neil Brown <neilb@cse.unsw.edu.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
