From 0552210997badb6a60740a26ff9d976a416510f0 Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Fri, 11 May 2018 13:13:31 -0700 Subject: [PATCH] Btrfs: don't BUG_ON() in btrfs_truncate_inode_items() btrfs_free_extent() can fail because of ENOMEM. There's no reason to panic here, we can just abort the transaction.
