xfs: handle "raw" delayed extents xfs_reflink_trim_around_shared
Delalloc extents in the extent list contain the number of reserved indirect blocks in their startblock value and don't use the magic DELAYSTARTBLOCK constant. Ensure that xfs_reflink_trim_around_shared handles them properly by checking for isnullstartblock(). Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
