Hi,
you may have noticed my patches for new FALLOC_FL_ZERO_RANGE
fallocate flag. 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.
Thanks!
-Lukas
