From 31ca03c92c329525ee3a97d99c47f1ebbaed5d63 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 8 Jan 2018 10:51:02 -0800 Subject: [PATCH] xfs: refactor xfs_verifier_error and xfs_buf_ioerror Since all verification errors also mark the buffer as having an error, we can combine these two calls. Later we'll add a xfs_failaddr_t parameter to promote the idea of reporting corruption errors and the address of the failing check to enable better debugging reports. Signed-off-by: Darrick J.
