From 08d2f347e877e489ca098c87a6fd2e872fef9767 Mon Sep 17 00:00:00 2001 From: Jan Schmidt Date: Wed, 4 May 2011 16:18:50 +0200 Subject: Btrfs: fix extent state leak on failed nodatasum reads When encountering an EIO while reading from a nodatasum extent, we insert an error record into the inode's failure tree. btrfs_readpage_end_io_hook returns early for nodatasum inodes. We'd better clear the failure tree in that case, otherwise the kernel complains about BUG extent_state: Objects remaining on kmem_cache_close() on rmmod.
