    drbd: Consider the disk-timeout also for meta-data IO operations · 32db80f6
    Philipp Reisner authored
    If the backing device is already frozen during attach, we failed
    to recognize that. The current disk-timeout code works on top
    of the drbd_request objects. During attach we do not allow IO
    and therefore never generate a drbd_request object but block
    before that in drbd_make_request().
    
    This patch adds the timeout to all drbd_md_sync_page_io().
    
    Before this patch we used to go from D_ATTACHING directly
    to D_DISKLESS if IO failed during attach. We can no longer
    do this since we have to stay in D_FAILED until all IO
    ops issued to the backing device returned.
