Re: FYI: v9fs/test rework

Hi Eric,

Glad to hear you're picking v9fs back up. In case any of it is useful as a reference point, I've been maintaining a fair amount of 9p CI for ZeroFS, exercising the Linux v9fs client against the ZeroFS server across a few transports and mount option combinations:

Not a generic test harness like what you're building, but there may be some scenarios or pitfalls in there worth borrowing, including xfstests:

Happy to answer questions if anything looks relevant.

Best,
Pierre
