Hi folks, I've been working on the implementation of FSEMAP ioctl as we've been discussed previously, and, the first discussion about this, was about using the same fiemap structures to retrieve free extents from the btrees. By our last chat about it (it's been a while, I know, I got busy with more important stuff :), Dave suggested another uses for FSEMAP that were not in my mind, so, I think it deserves its own implementation, independent of fiemap from where the same idea came from. So, I'd like to know, what else might FSEMAP be used for, beyond iterating free space extents, so I can think of a new struct to be exchanged between user<-> kernel. FSEMAP is supposed to complement GETFSMAPX, discussed in LSF this year, but I don't know if is there any plan to keep with GETFSMAPX or not, or even if FSEMAP is still a valuable idea :) Any comments, suggestions about to what direction should FSEMAP go?
