[PATCH 03/10] xfstests: rename RETAIN_AG_BYTES

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

Rename the $RETAIN_AG_BYTES variable to be more generic so that it
reflects the fact that it is designed to retain a certain amount of
extra free space above the default amount in the filesystem when
doing large scratch device testing.
