From 62c5ac89de7d5eecdbaa94ca3d554b0bd41578b1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 20 Oct 2016 15:52:00 +1100 Subject: [PATCH] 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 Reviewed-by: Darrick J.
