Sorry about that, I mean "amd64".
Actually I don't have performance numbers to proof that now. I think
it really depends on the detailed architecture hardware implementation.
In my opinion, I just think it is better to wrap it up rather than
do open-coded all around...
do {
cpu_relax()
} while(...);
I was just cleaning up EROFS file system, and saw these piece of code
(bit_spinlock) by chance. Therefore I write a patch to get some idea
about it....
Thanks,
