Subject: Re: [PATCH 1/2] mm: restrict access to slab files under procfs and
 sysfs

This also needs to other /proc files I believe,


Acked-by: Christoph Lameter <cl@...ux.com>


Possible candidates:

christoph@...y:~/n/linux-2.6$ grep proc_create mm/*
mm/swapfile.c:	proc_create("swaps", 0, NULL, &proc_swaps_operations);
mm/vmstat.c:	proc_create("buddyinfo", S_IRUGO, NULL, &fragmentation_file_operations);
mm/vmstat.c:	proc_create("pagetypeinfo", S_IRUGO, NULL, &pagetypeinfo_file_ops);
mm/vmstat.c:	proc_create("vmstat", S_IRUGO, NULL, &proc_vmstat_file_operations);
mm/vmstat.c:	proc_create("zoneinfo", S_IRUGO, NULL, &proc_zoneinfo_file_operations);

vmstat and zoneinfo in particular give similar information to what is
revealed through the slab proc files.
