Subject: mm: move page dirtying prototypes from mm.h
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3a6b2162005f24c7caa10d7f10dba487629787f2;p=linux.git

mm: move page dirtying prototypes from mm.h

These functions implement the address_space ->set_page_dirty operation and
should live in pagemap.h, not mm.h so that the rest of the kernel doesn't
get funny ideas about calling them directly.
