From 86e7366e84c29082ffcaf20c43e8239a10410d64 Mon Sep 17 00:00:00 2001 From: Eryu Guan Date: Thu, 26 May 2016 11:26:24 +0800 Subject: [PATCH] generic/250: ignore xfs_io IO errors when writing to dmerror device When testing with data=journal ext4, direct write to dmerror device doesn't return EIO, because ext4 turns direct write to buffered write in data=journal mode and all data is written to journal buffer. The write only fails later when commiting journal and error messages can be seen in dmesg. As the test is checking on the md5 checksum of the test file, it's ok to ignore the IO error returned by xfs_io, as long as the checksums match the golden image. Reviewed-by: Darrick J.
