Would you mind if I add "Tested-by" tags? Wouldn't mind at all. I've also run several of the filebench [1] workload personalities with this patched kernel for ten minutes a piece (i.e. the `fileserver' and `networkfs' personalities) and experienced no problems. During the tests I also added the blackhole route to the server several times (along with restarting the NFS server) and it recovered each time. I did this for filebench running SCHED_OTHER and SCHED_RR with a priority of 50. > Sure. I'll let you know as soon as I push them out later today... Cool, I'll keep an eye out.
