[zfs-discuss] Re: Porting ZFS file system to FreeBSD.

[Eric Schrock]

Congrats, Pawel.  This is truly an impressive piece of work.  As you're
probably aware, Noel integrated the patches your provided us into build
51.  Hopefully that got rid of some spurious differences between the
code bases.

We do have a program called 'ziltest' that Neil can probably provide for
you that does a good job stressing the ZIL.  We also have a complete
test suite (functional and stress), but it would be non-trivial to port,
and I don't know what the current status is for open sourcing the test
suites in general.

Let us know if there's anything else we can help with.
