Re: [PATCH 1/2] fs: add SEEK_HOLE and SEEK_DATA flags

We'll also need:

- a patch to lseek(2) to document the new flags
- some testcases for xfstests, specially dealing with things that
were problematic in FIEMAP, e.g. data in delalloc extents, making
sure stuff in unwrittent extents partially converted actually gets
copied, etc.
