[merged] mm-dont-pass-enum-lru_list-to-trace_mm_lru_insertion.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm/swap.c: don't pass "enum lru_list" to trace_mm_lru_insertion()
has been removed from the -mm tree.  Its filename was
     mm-dont-pass-enum-lru_list-to-trace_mm_lru_insertion.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Yu Zhao <yuzhao@google.com>
Subject: mm/swap.c: don't pass "enum lru_list" to trace_mm_lru_insertion()

The parameter is redundant in the sense that it can be extracted
from the "struct page" parameter by page_lru() correctly.
