Subject: [PATCHSET v6] fstests: support ext4 fuse testing
Hi all,
Various test adjustments to support testing the fuse ext4 server (fuse2fs) as
if it were the kernel ext4 driver. This supports QAing the fuse-iomap
prototype project.
If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.
This has been running on the djcloud for months with no problems. Enjoy!
Comments and questions are, as always, welcome.
