New Revision: 254996
URL: http://svnweb.freebsd.org/changeset/base/254996
Log:
In looking at block layouts as part of fixing filesystem block
allocations under low free-space conditions (-r254995), determine
that old block-preference search order used before -r249782 worked
a bit better. This change reverts to that block-preference search order.
