Subject: [patch 38/67] mm: pagewalk: add 'depth' parameter to pte_hole
Date: Mon, 03 Feb 2020 17:36:03 -0800
Message-ID: <20200204013603.Q2V-TR4Dr%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200203173311.6269a8be06a05e5a4aa08a93@linux-foundation.org>

From: Steven Price <steven.price@arm.com>
Subject: mm: pagewalk: add 'depth' parameter to pte_hole

The pte_hole() callback is called at multiple levels of the page tables. 
Code dumping the kernel page tables needs to know what at what depth the
missing entry is.  Add this is an extra parameter to pte_hole().  When the
depth isn't know (e.g.  processing a vma) then -1 is passed.

The depth that is reported is the actual level where the entry is missing
(ignoring any folding that is in place), i.e.  any levels where
PTRS_PER_P?D is set to 1 are ignored.

Note that depth starts at 0 for a PGD so that PUD/PMD/PTE retain their
natural numbers as levels 2/3/4.
