[Gluster-devel] rpc throttling causing ping timer expiries while running iozone

[Pranith Kumar Karampuri]

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.
