So, I could do xfs_zero_range(offset, offset_ru)[1] and xfs_zero_range(end_rd, end). (offset_ru, end_rd) will be using the accelerated XFS_BMAPI_ZERO to zero out the extents.
Yeah.
I also need to add pagecache_isize_extended and filemap_write_and_wait_range to persist the xfs_zero_range calls before we call setfilesize.
Yeah, Or we need to find a way to use xfs_falloc_setsize after all which would share all that code, although I'm not really sure how that would work best.
