I didn't see a response to my earlier email about the other uses of
min_t(int, x, INT_MAX) so I fixed it up myself and added this to my
tree. I don't have a working setup to test yet so please let me know
if you see anything wrong with this:

HR Here's a patch to fix this for OFED 1.3:
While you're there, can you change pointer dereference with memcpy,
e.g.:
memcpy (capmask, pc+2, sizeof(capmask));
capmask = ntohs(capmask);
Those pointer dereferenes are royal pain on ia64 unless
I'm not sure what you mean. During the 2.6.23 cycle I've been sending
any patches that potentially could conflict with the net-2.6 tree to
you and Jeff so that you can merge them upstream via your tree. Or do
you mean Jeff should become the maintainer of drivers/infiniband??

related to this comment, does Linux have a lockless (using atomics)

No; it doesn't. At least not a portable one.

to be as slow as an explicit
Use RCU? or write a generic version and get it reviewed. You really

I guess he was thinking of using cmpxchg; but we don't support this

RCU is not really suitable for this because it assume
I'd like to patch the OFED-1.2.5 source file ib_srp.h (or use the modified

local use. The goal is to have a local OFED distribution package

My setup is as follows:
I have 4 ports on a DDN, each port has 2 LUNs mapped to it.
I have 4 ports active on the SRP initiator machine. I want to do a one to

connected via a switch.
Here are the 4 ports as seen by SRP:
