Hi,

Several people have been interested to test my vfs patches, so rather
than resend patches I have uploaded a rollup against Linus's current
head.

ftp://ftp.kernel.org/pub/linux/kernel/people/npiggin/patc...

I have used ext2,ext3,autofs4,nfs as well as in-memory filesystems
OK (although this doesn't mean there are no bugs!). Otherwise, if your
filesystem compiles, then there is a reasonable chance of it working,
or ask me and I can try updating it for the new locking.

I would be interested in seeing any numbers people might come up with,
including single-threaded performance.

Thanks, Nick
