From 79befd0c08c4766f8fa27e37ac2a70e40840a56a Mon Sep 17 00:00:00 2001 From: Andrea Arcangeli Date: Sat, 16 Apr 2005 15:24:05 -0700 Subject: [PATCH] oom-killer disable for iscsi/lvm2/multipath userland critical sections iscsi/lvm2/multipath needs guaranteed protection from the oom-killer, so make the magical value of -17 in /proc//oom_adj defeat the oom-killer altogether. (akpm: we still need to document oom_adj and friends in Documentation/filesystems/proc.txt!)
