[dm-devel] [PATCH] dm raid1: the device-mapper 'mirror' target errors written bios erroneously

[heinzm at redhat.com]

From: Heinz Mauelshagen <heinzm at redhat.com>

	The device-mapper 'mirror' target errors correctly written
	bios erroneously in hold_bio() in case the mapped device is
	suspended and flushs are allowed.

	Because the caller already copes with erroring such bios in
	case all mirror legs got failed, any getting to hold_bio()
	are good, thus the patch sets bio->bi_error to 0.

	Resolves: rhbz1307111
