I think readmostliness and alignment are mostly-unrelated concepts and

__cacheline_aligned_mostly_readonly goes away and to handle things like the

Yup that makes the whole thing much more sane. Can we specify multiple attributes to a variable?


I suppose so.

Compiling this:

int x __attribute__((__aligned__(32)))
__attribute__((__section__(".data.mostly_readonly")));


Can I just throw in something unrelated and not very constructive
and ask that we call it 'read_mostly' instead of mostly_readonly?

mostly_readonly kind of says to me that most items in the section
are read only, read_mostly says all the items are mostly only read.
