We recommend running our "bricks" on top of XFS, so one of my goals has been to get more involved with XFS development as well. :) This was a nice little project for me to break some ground on (actually I have some associated XFS quota prealloc throttling changes in the works as well, but I'll prioritize the testing work here first). ;) >> Beyond testing via that, I just had a very >> simple/stupid program with the command and data structure bits >> copy/pasted in to open a file and invoke an xfsctl() with hardcoded >> parameters.
