>Description:
uninitialized variables in sys/compat/linprocfs/linprocfs.c
function: linprocfs_domeminfo()  i and j are uninitialized

you call swap_pager_status(&i, &j);

swap_pager_status does
  *i += sp->sw_nblks;
  *j += sp->sw_used;
 but i and j contain random data

>How-To-Repeat:
top reports wrong size for swap
cat /proc/meminfo has wrong size

has been reported before as kern/31048
still shows as open
>Fix:
solution: initialize i and j to 0 in linprocfs.c before call
