Chris Mason 546888da82 Btrfs: fix btrfs fallocate oops and deadlock ... Btrfs fallocate was incorrectly starting a transaction with a lock held on the extent_io tree for the file, which could deadlock. Strictly speaking it was using join_transaction which would be safe, but it is better to move the transaction outside of the lock. When preallocated extents are overwritten, btrfs_mark_buffer_dirty was being called on an unlocked buffer. This was triggering an assertion and oops because the lock is supposed to be held. The bug was calling btrfs_mark_buffer_dirty on a leaf after btrfs_del_item had been run. btrfs_del_item takes care of dirtying things, so the solution is a to skip the btrfs_mark_buffer_dirty call in this case.
