This changes things around the same area as your patches does so we should probably figure out which are going to land in first and then rebase the other on top of that. One concern I have is that I have not seen any tests provided to verify the feature. But I just may have missed it. Do you have any xfstests test or at least fsx and fsstress patches to provide support for testing FALLOC_FL_COLLAPSE_RANGE ? Patches for util_linux might also be handy.
