What is the perspective of these patches, hanging in a queue for more
then a month? I hit this problem on FreeBSD, and this patch seems
significantly improves the UNMAP performance.

The status is: I'm was a little slow to email the advocates, but I'm now
working the the advocates to integrate this (I'm going to be merging the
two commits and fixing up the messages, etc). Currently, I'm testing that
my changes still work after I rebase from master, but I hope to be ready
for integration later this week.

Best,
~Alex
