xprtrdma: Squelch kbuild sparse complaint
commit eed50879d64ab1b9f76445dbab822e43a098b309 upstream.
New complaint from kbuild for 4.9.y:
net/sunrpc/xprtrdma/verbs.c:489:19: sparse: incompatible types in
comparison expression (different type sizes)
verbs.c:
489 max_sge = min(ia->ri_device->attrs.max_sge, RPCRDMA_MAX_SEND_SGES);
I can't reproduce this running sparse here. Likewise, "make W=1
net/sunrpc/xprtrdma/verbs.o" never indicated any issue.
A little poking suggests that because the range of its values is
small, gcc can make the actual width of RPCRDMA_MAX_SEND_SGES
smaller than the width of an unsigned integer.
Fixes: 16f906d66cd7 ("xprtrdma: Reduce required number of send SGEs")
