Subject: mm: dump page when hitting a VM_BUG_ON using VM_BUG_ON_PAGE
X-Git-Tag: v4.0~2547^2~188
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=309381feaee564281c3d9e90fbca8963bb7428ad;p=platform%2Fkernel%2Flinux-amlogic.git

mm: dump page when hitting a VM_BUG_ON using VM_BUG_ON_PAGE

Most of the VM_BUG_ON assertions are performed on a page.  Usually, when
one of these assertions fails we'll get a BUG_ON with a call stack and
the registers.

I've recently noticed based on the requests to add a small piece of code
that dumps the page to various VM_BUG_ON sites that the page dump is
quite useful to people debugging issues in mm.

This patch adds a VM_BUG_ON_PAGE(cond, page) which beyond doing what
VM_BUG_ON() does, also dumps the page before executing the actual
BUG_ON.
