Date: Sat, 09 Feb 2008 15:40:12 -0700 From: Larry Finger <Larry.Finger@...inger.net> To: LKML <linux-kernel@...r.kernel.org> Subject: Query about set_pages_* API Is the set_pages_* API that replaces change_page_attr described somewhere? I have been unable to find it with Google. I'm trying to modify the VirtualBox kernel module to work with 2.6.24-git (and 2.6.25) on x86_64 architecture. The current code has a value of the third argument of the call (prot) with 3 variants. All variations have the following bits set: _PAGE_PRESENT, _PAGE_RW, _PAGE_DIRTY, and _PAGE_ACCESSED. Number 2 adds _PAGE_NX to the above, and number 3 adds _PAGE_GLOBAL to the bits in variation 1. From the code in arch/x86/mm/pageattr.c, I figured I need to call set_pages_wb() unconditionally, and set_pages_nx() if _PAGE_NX is set. Will these calls be sufficient? I thought about calling set_pages_rw(), but that entry is not exported.
