Hi Steve-

Thanks for digging into this.

I can't tell, but have you addressed the problem of racing processes generating multiple similar ACCESS requests? Seems like some kind of serialization through your caching mechanism would resolve that nicely.
No.. I was just trying to duplicate logic that was there...
but that is a good point... It turns out that I messed up the
locking anyways... the NFS_INO_INVALID_ACCESS bit is no longer
being protect by the inode->i_lock which is not good... so I
need to rework that part...
