From cc95bef635a649d595cf8d1cd4fcff5b6bf13023 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 4 Apr 2013 14:31:27 -0400 Subject: Btrfs: log ram bytes properly When logging changed extents I was logging ram_bytes as the current length, which isn't correct, it's supposed to be the ram bytes of the original extent. This is for compression where even if we split the extent we need to know the ram bytes so when we uncompress the extent we know how big it will be. This was still working out right with compression for some reason but I think we were getting lucky. It was definitely off for prealloc which is why I noticed it, btrfsck was complaining about it. With this patch btrfsck no longer complains after a log replay.
