Comment 10 for bug 872905

Hand tested this on precise: Linux ubuntu 3.2.0-30-generic #47-Ubuntu SMP Wed Aug 15 19:30:10 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Created lower ext2 file system, mounted ecryptfs on top. Filled lower to full, attempted to create file in upper, got full disk, file was not created and there was no zero byte lower ecrypted file created either.

If I repeated this on an older kernel, we get zero byte lower ecrypted files created, thus showing the older kernels manifest this bug where as the -proposed kernel fixes this issue.
