From a9febbb4bd1302b6f01aa1203b0a804e4e5c9e25 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 15 Oct 2010 14:34:12 -0700 Subject: sysctl: min/max bounds are optional sysctl check complains with a WARN() when proc_doulongvec_minmax() or proc_doulongvec_ms_jiffies_minmax() are used by a vector of longs (with more than one element), with no min or max value specified. This is unexpected, given we had a bug on this min/max handling :) Reported-by: Jiri Slaby Signed-off-by: Eric Dumazet Cc: "Eric W.
