Re: Kernel v4.16 / v4.17 SRP and SRPT patches

Hi Bart

So after sorting out the panic issue I started full testing of your
patch sets for SRPT and SRP.

This is the fisrt time i am using your kernel for both the SRPT side
(server) and SRP side (Client)

Server and Client both running kernel off your tree

[root@fedstorage ~]# uname -a
Linux fedstorage.bos.redhat.com 4.15.0-rc7.bart+ #1 SMP Thu Jan 11
14:17:33 EST 2018 x86_64 x86_64 x86_64 GNU/Linux

Prior to booting the Server on your tree I could find my LUNS,
I was using 4.15 from Mike Snitzers tree for the server.

Now I see this on probe for SRP devices.

I have not changed any configuration entries for the srpt driver.

Still at
[root@fedstorage modprobe.d]# cat ib_srpt.conf 
options ib_srpt srp_max_req_size=8296 srpt_srq_size=32768
