Eric Biggers	81966d8349	fs/proc/util.c: include fs/proc/internal.h for name_to_int() ... name_to_int() is defined in fs/proc/util.c and declared in fs/proc/internal.h, but the declaration isn't included at the point of the definition. Include the header to enforce that the definition matches the declaration. This addresses a gcc warning when -Wmissing-prototypes is enabled.
