From 7813b3db0a9ec77ff1f4b3ee3fb4925848395d59 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Mon, 10 Feb 2014 17:37:25 +0800 Subject: [PATCH] Btrfs: avoid warning bomb of btrfs_invalidate_inodes So after transaction is aborted, we need to cleanup inode resources by calling btrfs_invalidate_inodes(), and btrfs_invalidate_inodes() hopes roots' refs to be zero in old times and sets a WARN_ON(), however, this is not always true within cleaning up transaction, so we get to detect transaction abortion and not warn at all.
