From 9503c67c93ed0b95ba62d12d1fd09da6245dbdd6 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Mon, 7 Apr 2014 10:54:20 -0400 Subject: ext4: note the error in ext4_end_bio() ext4_end_bio() currently throws away the error that it receives. Chances are this is part of a spate of errors, one of which will end up getting the error returned to userspace somehow, but we shouldn't take that risk. Also print out the errno to aid in debug.
