Subject: [patch 078/143] mm: replace migrate_[prep|finish] with lru_cache_[disable|enable]
Date: Tue, 04 May 2021 18:36:57 -0700	[thread overview]
Message-ID: <20210505013657.uv5tKrPa6%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210504183219.a3cc46aee4013d77402276c5@linux-foundation.org>

From: Minchan Kim <minchan@kernel.org>
Subject: mm: replace migrate_[prep|finish] with lru_cache_[disable|enable]

Currently, migrate_[prep|finish] is merely a wrapper of
lru_cache_[disable|enable].  There is not much to gain from having
additional abstraction.

Use lru_cache_[disable|enable] instead of migrate_[prep|finish], which
would be more descriptive.

note: migrate_prep_local in compaction.c changed into lru_add_drain to
avoid CPU schedule cost with involving many other CPUs to keep old
behavior.
