Re: [PATCH -mm] utrace: nommu fixup support utrace

[Roland McGrath]

That old ptrace check seems pretty questionable to me.  I think what you
want is for the nommu world's get_user_pages/access_process_vm when called
with force=1,write=1 on a read-only MAP_PRIVATE page to do something more
morally similar to the mmu world's COW than it does now.


Thanks,
Roland
