    Btrfs: account for space used by the super mirrors · 1b2da372
    Josef Bacik authored
    As we get closer to proper -ENOSPC handling in btrfs, we need more accurate
    space accounting for the space info's.  Currently we exclude the free space for
    the super mirrors, but the space they take up isn't accounted for in any of the
    counters.  This patch introduces bytes_super, which keeps track of the amount
    of bytes used for a super mirror in the block group cache and space info.  This
    makes sure that our free space caclucations will be completely accurate.
