From 878520ac45f9f698432d4276db3d9144b83931b6 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Tue, 19 Nov 2019 21:54:15 -0500 Subject: ext4: save the error code which triggered an ext4_error() in the superblock This allows the cause of an ext4_error() report to be categorized based on whether it was triggered due to an I/O error, or an memory allocation error, or other possible causes. Most errors are caused by a detected file system inconsistency, so the default code stored in the superblock will be EXT4_ERR_EFSCORRUPTED.
