From 882895d4119992af2c9b654dbb3ac88cd17fa810 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Thu, 3 Nov 2011 12:17:49 -0400 Subject: [PATCH] Btrfs: fix raid10 reading math The btrfs-progs raid10 code has been silently reading the wrong raid10 block forever. We didn't notice because it was always fixed up by the retry code.
