    btrfs: Moved repair code from inode.c to extent_io.c · 4a54c8c1
    Jan Schmidt 提交于
    The raid-retry code in inode.c can be generalized so that it works for
    metadata as well. Thus, this patch moves it to extent_io.c and makes the
    raid-retry code a raid-repair code.
    
    Repair works that way: Whenever a read error occurs and we have more
    mirrors to try, note the failed mirror, and retry another. If we find a
    good one, check if we did note a failure earlier and if so, do not allow
    the read to complete until after the bad sector was written with the good
    data we just fetched. As we have the extent locked while reading, no one
    can change the data in between.
