From eb965eda1cabf26e62afc07a06cdf2fd5aaa2906 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Wed, 12 Jul 2017 14:33:52 -0700 Subject: test_sysctl: add simple proc_dointvec() case Test against a simple proc_dointvec() case. While at it, add a test against INT_MAX. Make sure INT_MAX works, and INT_MAX+1 will fail. Also test negative values work. Link: http://lkml.kernel.org/r/20170630224431.17374-5-mcgrof@kernel.org Signed-off-by: Luis R.
