-Subject: mm: fix mlock accouting
-
-From: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
-
-commit 7162a1e87b3e380133dadc7909081bb70d0a7041 upstream.
-
-Tetsuo Handa reported underflow of NR_MLOCK on munlock.
-
-Testcase:
-
-    #include <stdio.h>
-    #include <stdlib.h>
-    #include <sys/mman.h>
-
-    #define BASE ((void *)0x400000000000)
-    #define SIZE (1UL << 21)
-
-    int main(int argc, char *argv[])
-    {
-        void *addr;
-
-        system("grep Mlocked /proc/meminfo");
-        addr = mmap(BASE, SIZE, PROT_READ | PROT_WRITE,
-                MAP_ANONYMOUS | MAP_PRIVATE | MAP_LOCKED | MAP_FIXED,
-                -1, 0);
-        if (addr == MAP_FAILED)
-            printf("mmap() failed\n"), exit(1);
-        munmap(addr, SIZE);
-        system("grep Mlocked /proc/meminfo");
-        return 0;
-    }
-
-It happens on munlock_vma_page() due to unfortunate choice of nr_pages
-data type:
-
-    __mod_zone_page_state(zone, NR_MLOCK, -nr_pages);
-
-For unsigned int nr_pages, implicitly casted to long in
-__mod_zone_page_state(), it becomes something around UINT_MAX.
-
-munlock_vma_page() usually called for THP as small pages go though
-pagevec.
-
-Let's make nr_pages signed int.
-
-Similar fixes in 6cdb18ad98a4 ("mm/vmstat: fix overflow in
-mod_zone_page_state()") used `long' type, but `int' here is OK for a
-count of the number of sub-pages in a huge page.
-
-Fixes: ff6a6da60b89 ("mm: accelerate munlock() treatment of THP pages")
