Josef Bacik dcab6a3b2a Btrfs: account for large extents with enospc ... On our gluster boxes we stream large tar balls of backups onto our fses. With 160gb of ram this means we get really large contiguous ranges of dirty data, but the way our ENOSPC stuff works is that as long as it's contiguous we only hold metadata reservation for one extent. The problem is we limit our extents to 128mb, so we'll end up with at least 800 extents so our enospc accounting is quite a bit lower than what we need. To keep track of this make sure we increase outstanding_extents for every multiple of the max extent size so we can be sure to have enough reserved metadata space.
