3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Josef Bacik <[email protected]> commit 2adcac1a7331d93a17285804819caa96070b231f upstream. If cow_file_range_inline fails with ENOSPC we abort the transaction which isn't very nice. This really shouldn't be happening anyways but there's no sense in making it a horrible error when we can easily just go allocate normal data space for this stuff.
