master - report: add separate LVSINFOSTATUS field type for info+status combined fields

by Peter Rajnoha

Commit: 158e9988768be344c0c97acdf52d1c020ab8c83e Parent: 75b786c5ef557b690e5638b6702ad19f20cb13f1 Author: Peter Rajnoha <prajnoha(a)redhat.com> AuthorDate: Tue Jan 20 16:02:48 2015 +0100 Committer: Peter Rajnoha <prajnoha(a)redhat.com> CommitterDate: Tue Jan 20 16:10:59 2015 +0100 report: add separate LVSINFOSTATUS field type for info+status combined fields Add separate LVSINFOSTATUS field type for fields which display both dm info-like and dm status-like information. The internal interface is there with the introduction of LVSSTATUS field type which can cope with the combination of LVSSTATUS and LVSINFO field types (several fields). However, till now, we considered that *single* field can display either LVSINFO or LVSSTATUS, but not both at the same time. Till now, we haven't had single field which needs both - hence add LVSINFOSTATUS field type for such fields as we currently need this for the lv_attr field which requires combination of info and status. This patch just adds interface for an ability to register such fields (the code that copes with this is already in). --- lib/report/columns.h | 2 +- lib/report/report.c | 1 + lib/report/report.h | 15 ++++++++------- tools/reporter.c | 12 +++++++----- 4 files changed, 17 insertions(+), 13 deletions(-) diff --git a/lib/report/columns.h b/lib/report/columns.h index 2b788c1..25eca80 100644 --- a/lib/report/columns.h +++ b/lib/report/columns.h @@ -38,7 +38,7 @@ FIELD(LVS, lv, STR, "LV", lvid, 4, lvfullname, lv_full_name, "Full name of LV in FIELD(LVS, lv, STR, "Path", lvid, 4, lvpath, lv_path, "Full pathname for LV.
