The patch titled
Subject: mm: vmscan: remove noinline_for_stack
has been removed from the -mm tree. Its filename was
mm-vmscan-remove-noinline_for_stack.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Muchun Song <songmuchun@xxxxxxxxxxxxx>
Subject: mm: vmscan: remove noinline_for_stack
The noinline_for_stack is introduced by commit 666356297ec4 ("vmscan: set
up pagevec as late as possible in shrink_inactive_list()"), its purpose is
to delay the allocation of pagevec as late as possible to save stack
memory. But the commit 2bcf88796381 ("mm: take pagevecs off reclaim
stack") replace pagevecs by lists of pages_to_free. So we do not need
noinline_for_stack, just remove it (let the compiler decide whether to
inline).
