From fa5c836ca8eb5bad6316ddfc066acbc4e2485356 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 20 Oct 2016 15:54:14 +1100 Subject: xfs: refactor xfs_bunmapi_cow Split out two helpers for deleting delayed or real extents from the COW fork. This allows to call them directly from xfs_reflink_cow_end_io once that function is refactored to iterate the extent tree. It will also allow to reuse the delalloc deletion from xfs_bunmapi in the future. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J.
