Subject: [PATCH 0/5] mm/treewide: Replace pXd_large() with pXd_leaf()
Date: Wed, 28 Feb 2024 16:53:45 +0800 [thread overview]
Message-ID: <20240228085350.520953-1-peterx@redhat.com> (raw)
From: Peter Xu <peterx@redhat.com>
[based on latest akpm/mm-unstable, commit 1274e7646240]
These two APIs are mostly always the same. It's confusing to have both of
them. Merge them into one. Here I used pXd_leaf() only because pXd_leaf()
is a global API which is always defined, while pXd_large() is not.
We have yet one more API that is similar which is pXd_huge(), but that's
even trickier, so let's do it step by step.
Some cautions are needed on either x86 or ppc: x86 is currently the only
user of p4d_large(), while ppc used to define pXd_large() only with THP,
while it is not the case for pXd_leaf(). For the rest archs, afaict
they're 100% identical.
Only lightly tested on x86.
Please have a look, thanks.
