There are a number of sparse warnings coming
from the fs subdirectory, mainly due to not
defining functions that are used by other files,
as well as 0/NULL patch to fs/proc/task_mmu.c
This patch creates a header with the definitions
in and includes it into the relevant .c files,
and moves the proc definitions into
linux/proc_fs.h
Also cleans up some static definitions in
fs/inotify.c
