Subject: autofs: move inclusion of linux/limits.h to uapi
linux/limits.h should be included by uapi instead of linux/auto_fs.h
so as not to cause compile error in userspace.
# cat << EOF > ./test1.c
> #include <stdio.h>
> #include <linux/auto_fs.h>
> int main(void) {
> return 0;
> }
> EOF
# gcc -Wall -g ./test1.c
In file included from ./test1.c:2:0:
/usr/include/linux/auto_fs.h:54:12: error: 'NAME_MAX' undeclared here (not in a function)
char name[NAME_MAX+1];
