Hi Randy,

Sorry for the poor explanation. I see that I left out the specific header.
The inclusion of linux/sunrpc/svc_rdma.h brings in linux/sunrpc/rpc_rdma.h
This brings in linux/bitops.h which is preferred over asm/bitops.h

Yes, this conflicts with Rule #1. A better version of this patch would be to add
linux/bitops.h to this file directly. The main reason this patch
exists is to clear
out the asm-generic file since those are not preferred. I can do this by either
including just linux/bitops.h or including both linux/bitops.h and
asm/barrier.h.
Would the second approach conform better with Rule #1?

Thanks,
Tanzir
