Subject: mm/vmscan: rename zone_nr_pages() to zone_nr_lru_pages()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b21767637c3c99890a248fe47ac414e51cf5eb7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mm/vmscan: rename zone_nr_pages() to zone_nr_lru_pages()

The name `zone_nr_pages' can be mis-read as zone's (total) number pages,
but it actually returns zone's LRU list number pages.
