And there is no need for that, too - just untie this value from the page size instead, and fix the munmap issue in the runtime library by up/down aligning the bounds to the runtime page size. You can also increase the default / minimal ring buffer size at runtime to be a multiple of the page size.

Sorry, my expression may not be accurate at first. I want to support more kind of page size for HWAsan. I add a command option to custom page size in D123908 <https://reviews.llvm.org/D123908>. 
I think the runtime can know the real page size by sysconf syscall adaptively.

Thanks!
