Subject: 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.
