Note that you need to place your syncop code in a synctask function strictly within a syncenv (by calling synctask_new(). You're probably calling syncop_XXX() directly in your xlator code?

Hello everyone,I am trying to use syncops in a custom translator to keep my code at least borderline readable, but I am having limited success.
Problem Symptoms:
Using a syncop in a regular fop is fine. However, in a callback it causes a 'freeze' (synctask_yield called by the SYNCOP macro doesn't return).What seems to be the Problem:Looking at the traces, there is no corresponding trace from rpc_clnt_reply_init on the client to the trace from rpcsvc_submit_generic on the server. In other words, the rpc reply gets sent but isn't correctly received. Obviously this is not really a networking problem but something else... I'd guess it's a deadlock somewhere on the client?From the point of the syncop call onwards the client doesn't 'get' any rpc replies any more (the next GlusterFS Handshake sent by the client, which is received by the server and replied to, leads to a disconnection accordingly).Again: This problem is only occurring when calling a syncop from a callback function inside my translator, if I call the same syncop in a fop call it completes fine.
I hope you can make sense out of the above problem description.Thanks for your time ~
