From 2911edb653b9c64e0aad461f308cae8ce030eb7b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 20 Nov 2019 09:46:05 -0800 Subject: [PATCH] xfs: remove the mappedbno argument to xfs_da_get_buf Use the xfs_da_get_buf_daddr function directly for the two callers that pass a mapped disk address, and then remove the mappedbno argument.
