Saw a lot of (or similar in a private helper):
*(__be32 *)ptr = cpu_to_be32(val);
So I came up with
void put_be32(val, ptr);
This looked a lot like the put_unaligned_be32 helpers and only left a gap that was get_be32(ptr).
But this was exactly the same as the existing be32_to_cpup, so I wasn't sure if I should add it or not. In the end I just went ahead and did it and wanted to see what the patch would be like moving over existing users to the new api looked like.
On top of that I did the cpu_to_be32p removal, which probably was not the brightest thing ever.
So, that leaves (repeat for various endian values, be32 is an example):
1) should put_be32(val, ptr) be added (it seems useful and lots of code is already rolling their own if they aren't opencoding it)
2) should get_be32 be added purely to have a symmetric api, even through it is equivalent to be32_to_cpup? (nice that it looks just like get_unaligned_be32...makes alignment explicit)
3) if 2) should existiing be32_to_cpup users be moved over to the new api
4) if 3) should cpu_to_be32p be moved/changed at all (unlikely)
I hope that explains where I was coming from with this set of patches.
Harvey
