Subject: sysctl: min/max bounds are optional
From: Eric Dumazet <eric.dumazet@gmail.com>
sysctl check complains 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 :)
