This looks good to me but maybe someone more familiar with the oshmem component should take a look (@janjust)

I don't understand how this fixes the issue as you replace a bitwise and (so any bits could match) with a strict matching equality. The & would trigger in all the cases where == is true, and more.

I reread the discussion in #13060 and I now think this is a correct patch but not for the reason claimed in the PR log, but because it ensures a strict matching on the context options. Additionally it also covers the case of selecting contexts with no options, which is a plus. I suggest you change the log to make this clear.
