Subject: [lustre-devel] [PATCH 20/49] lustre: uapi: remove OBD_IOC_LOV_GET_CONFIG
Date: Thu, 15 Apr 2021 00:02:12 -0400	[thread overview]
Message-ID: <1618459361-17909-21-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1618459361-17909-1-git-send-email-jsimmons@infradead.org>

From: Andreas Dilger <adilger@whamcloud.com>

The "lctl lov_getconfig" command has been obsolete for some time,
but was kept around for sanity test_44a to work properly.  Now
that LU-11656 has landed, "lfs getstripe -d $DIR" can be used to
get the actual layout used for files created in a directory.

Remove the lov_getconfig command along with the IOC definition
it was using.

WC-bug-id: https://jira.whamcloud.com/browse/LU-13107
