Hi,

This an attempt to order the received responses using txid. It uses a hash table to do the reodering. I also took into account the case where txid is equal to 0xFF (any response is returned).

However, I am encountering a deadlock:

[  167.290298] dsm_lock: task dsm-conn/0:4 DEADLOCK on gfn[1298023] vfn[34107656807] caller ivy_kvm_dsm_handle_req
[  179.096223] dsm_lock: task dsm-conn/0:4 DEADLOCK on gfn[1298023] vfn[34107656807] caller ivy_kvm_dsm_handle_req
[  190.892436] dsm_lock: task dsm-conn/0:4 DEADLOCK on gfn[1298023] vfn[34107656807] caller ivy_kvm_dsm_handle_req
[  202.678218] dsm_lock: task dsm-conn/0:4 DEADLOCK on gfn[1298023] vfn[34107656807] caller ivy_kvm_dsm_handle_req
...

Any idea on the issue?
