hi,
When iozone is in progress and the number of blocking inodelks is greater
than the threshold number of rpc requests allowed for that client
(RPCSVC_DEFAULT_OUTSTANDING_RPC_LIMIT), subsequent requests from that client
will not be read until all the outstanding requests are processed and replied
to. But because no more requests are read from that client, unlocks on the
already granted locks will never come thus the number of outstanding requests
would never come down. This leads to a ping-timeout on the client. I am
wondering if the proper fix for this is to not account INODELK/ENTRYLK/LK calls
for throttling. I did make such a change in the codebase and tested it and it
works. Please let me know if this is acceptable or it needs to be fixed
differently.
