fs/file: more unsigned file descriptors
Propagate unsignedness for grand total of 149 bytes:
$ ./scripts/bloat-o-meter ../vmlinux-000 ../obj/vmlinux
add/remove: 0/0 grow/shrink: 0/10 up/down: 0/-149 (-149)
function old new delta
set_close_on_exec 99 98 -1
put_files_struct 201 200 -1
get_close_on_exec 59 58 -1
do_prlimit 498 497 -1
do_execveat_common.isra 1662 1661 -1
__close_fd 178 173 -5
do_dup2 219 204 -15
seq_show 685 660 -25
__alloc_fd 384 357 -27
dup_fd 718 646 -72
It mostly comes from converting "unsigned int" to "long" for bit operations.
