[merged] mm-gup_benchmark-gup_benchmark-depends-on-debug_fs.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm/gup_test: GUP_TEST depends on DEBUG_FS
has been removed from the -mm tree.  Its filename was
     mm-gup_benchmark-gup_benchmark-depends-on-debug_fs.patch

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

From: Barry Song <song.bao.hua@hisilicon.com>
Subject: mm/gup_test: GUP_TEST depends on DEBUG_FS

Without DEBUG_FS, all the code in gup_benchmark becomes meaningless.
For sure kernel provides debugfs stub while DEBUG_FS is disabled, but
the point here is that GUP_TEST can do nothing without DEBUG_FS.
