[merged] mm-page_alloc-make-should_fail_alloc_page-a-static-function-should_fail_alloc_page-static.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm/page_alloc: make should_fail_alloc_page() static
has been removed from the -mm tree.  Its filename was
     mm-page_alloc-make-should_fail_alloc_page-a-static-function-should_fail_alloc_page-static.patch

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

------------------------------------------------------
From: Mel Gorman <mgorman@techsingularity.net>
Subject: mm/page_alloc: make should_fail_alloc_page() static

make W=1 generates the following warning for mm/page_alloc.c

  mm/page_alloc.c:3651:15: warning: no previous prototype for `should_fail_alloc_page' [-Wmissing-prototypes]
   noinline bool should_fail_alloc_page(gfp_t gfp_mask, unsigned int order)
                 ^~~~~~~~~~~~~~~~~~~~~~

This function is deliberately split out for BPF to allow errors to be
injected.  The function is not used anywhere else so it is local to the
file.  Make it static which should still allow error injection to be used
similar to how block/blk-core.c:should_fail_bio() works.
