Why do we want userspace to know about whether skip_kasan_poison is set?
That seems like a kernel-internal detail to me.
the skip_kasan_poison also a page flags, we use page_types tool to display
them not only include user-internal,
but also kernel-internal, add them, the page-types tool can more detail
display the kernel-internal page flags,
just in case we don't miss some page flags when check the whole memory.
So you're just being completist? You don't have a reason to expose this
information?
Yes, about the skip_kasan_poison, i just want the kpageflags to support
it, i think it should be included,
the mainly region is i want get the page node info from the kpageflags
in my next patch, when i check these
codes, i see there lost some info about the skip_kasan_poison and young
flags, the page_types tool also check
the kasan pages, so i think it should be included.
Thanks.
