From bbae10fac2dceb6c8585d385cc689f4e7ce81b1f Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Fri, 8 May 2020 09:18:03 -0500 Subject: [PATCH] gfs2: Don't ignore inode write errors during inode_go_sync Before for this patch, function inode_go_sync ignored io errors during inode_go_sync, overwriting them with metadata write errors: error = filemap_fdatawait(mapping); mapping_set_error(mapping, error); } error = filemap_fdatawait(metamapping); ... return error; So any errors returned by the inode write would be forgotten if the metadata write succeeded. This patch still does both writes, but only sets error if it's still zero. That way, any errors will be reported by to the caller, do_xmote, which will take appropriate action and report the error.
