fs/ramfs/file-nommu.c: make ramfs_nommu_get_unmapped_area() and ramfs…

…_nommu_mmap() static Since commit 853ac43 ("shmem: unify regular and tiny shmem"), ramfs_nommu_get_unmapped_area() and ramfs_nommu_mmap() are not directly referenced outside of file-nommu.c. Thus make them static. Signed-off-by: Axel Lin <[email protected]> Cc: Al Viro <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
