From 1693918e0b6988cf5eb93b7da34f30e94360a379 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 26 Sep 2009 17:43:59 -0400 Subject: [PATCH] ext4: Use ext4_msg() for ext4_da_writepage() errors This allows the user to see what filesystem was involved with a particular ext4_da_writepage() error. Also, use KERN_CRIT which is more appropriate than KERN_EMERG.
