From 625a28a7e60c7c026e4d2929c49c8461fad4b0f3 Mon Sep 17 00:00:00 2001 From: Luis Chamberlain Date: Mon, 27 Sep 2021 15:02:58 -0700 Subject: swim: add error handling support for add_disk() We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. Since we have a caller to do our unwinding for the disk, and this is already dealt with safely we can re-use our existing error path goto label which already deals with the cleanup.
