Btrfs: fall back to non-inline if we don't have enough space
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. Thanks,
