Regression test for btrfs send where long paths (exceeding 230 characters)
made send produce paths with random characters from a memory buffer returned
by kmalloc, as send forgot to populate the new buffer with the path string.

This issue is fixed by the following linux kernel btrfs patch:

   Btrfs: send, fix corrupted path strings for long paths
