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@xxxxxxxxx>
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.
