From 085549553dca86c866f26d233d9cfe19f169c288 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 9 Nov 2016 14:42:49 -0800 Subject: ocfs2: don't eat io errors during _dio_end_io_write ocfs2_dio_end_io_write eats whatever errors may happen, which means that write errors do not propagate to userspace. Fix that. Signed-off-by: Darrick J.
