+Subject: Btrfs: fall back to non-inline if we don't have enough space
+
+From: Josef Bacik <josef@redhat.com>
+
+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,
+
