Subject: [PATCH 05/20] staging/lustre: remove alloc_fail_rate sysctl
Date: Mon, 6 Jul 2015 12:48:43 -0400 [thread overview]
Message-ID: <1436201338-14263-6-git-send-email-green@linuxhacker.ru> (raw)
In-Reply-To: <1436201338-14263-1-git-send-email-green@linuxhacker.ru>
From: Oleg Drokin <green@linuxhacker.ru>
It was used to control allocation failure rate, but there is
in-kernel way of doing that that's more versatile too.
This is going to remove just the sysctl, the underlying variable
will be removed once all OBD_ALLOC* macros removal patchseries land.
