asm-generic/barrier.h and asm/bitops.h are already brought into the
header and the file can still be built with their removal.

Brought into which header?

Does this conflict with Rule #1 in Documentation/process/submit-checklist.rst ?

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

Yes, it would IMO.

Where can I find your current working list of what/how to #include?

Thanks.

Hi Randy,

> Where can I find your current working list of what/how to #include?
 Here is my current working list of what to #include.

#include <linux/bitops.h>
#include <linux/interrupt.h>
#include <linux/slab.h>
#include <linux/sunrpc/addr.h>
#include <linux/sunrpc/svc_rdma.h>
#include <linux/log2.h>

#include <asm/barrier.h>

#include <rdma/ib_cm.h>

#include "xprt_rdma.h"
#include <trace/events/rpcrdma.h>

There was a discussion here about when to include asm/asm-generics:
https://lore.kernel.org/llvm/20231215210344.GA3096493@ZenIV/

If I misunderstood your question please let me know.

Best,
Tanzir

Yes, more the latter link for general info rather than the specific
info for this one source file.

Thanks.
