This is not a regression; the changes in this particular release will not cause this behaviour. The underlying issue is that the test fills the lower btrfs file system to a point where we run out of free space when searching for a free extent; see find_free_extent(). This error occurs when a chunk alloc fails. btrfs seems to handle these -ENOSPC errors poorly for some reason.

I think we can safely say that this is not an eCryptfs regression, but an existing bug in btrfs.
