[PATCH 09/12] staging/lustre/obdclass: remove llog_test.ko
Oleg Drokin
green at linuxhacker.ru
Sat Aug 30 21:12:48 UTC 2014
From: "John L. Hammond" <john.hammond at intel.com>
The llog_test module requires server support (it needs a local MGS to
function) and should not have been included.
Signed-off-by: John L. Hammond <john.hammond at intel.com>
