The patch titled
     Subject: include/linux/mm.h: add prototype for __add_to_page_cache_locked()
has been removed from the -mm tree.  Its filename was
     mm-add-prototype-for-__add_to_page_cache_locked.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
From: Souptick Joarder <jrdr.linux@gmail.com>
Subject: include/linux/mm.h: add prototype for __add_to_page_cache_locked()

Otherwise it causes a gcc warning:

../mm/filemap.c:830:14: warning: no previous prototype for
`__add_to_page_cache_locked' [-Wmissing-prototypes]

A previous attempt to make this function static led to compilation
errors for a few architectures, because __add_to_page_cache_locked() is
referred to by BPF code.

Adding a prototype will silence the warning.
