The argument against this patch is -- it should not be baked into the ABI as yet, since we do not have clarity on what applications need.
As it stands today the only way to figure out the information from userspace is by probing the kernel through calls to sys_pkey_alloc().
AT_HWCAP can be used, but that will certainly not be capable of providing all the information that userspace might expect.
Your thoughts?
Well, there's one well known application wanting that whole keys business, so why not ask them what works for them ?
In the meantime, that shouldn't block the rest of the patches.
Cheers, Ben.
