[PATCH 0/8] xfsprogs: new resvsp db command, plus some fixes

[Alex Elder]

The original purpose for this series was to add a new
"resvsp" command to xfs_db, to provide access to the
xfsctl(3) XFS_IOC_RESVSP64 operation.  Kevan Rehm did
this work, and along the way he found and fixed a few
cases where things weren't getting flushed to disk
properly.  I also looked things over and came up with
a few other small fixes.

I'm submitting the resulting series on Kevan's behalf.
I think we'll want to follow this up with at least one
test in the xfstests suite to exercise this new command.
