Subject: Revert "Btrfs: increase the global block reserve estimates"
From: Chris Mason <[email protected]>
commit 8e62c2de6e23e5c1fee04f59de51b54cc2868ca5 upstream.
This reverts commit 5500cdbe14d7435e04f66ff3cfb8ecd8b8e44ebf.
We've had a number of complaints of early enospc that bisect down
to this patch. We'll hae to fix the reservations differently.
