Subject: [Xen-devel] [PATCH OSSTEST v5 2/5] host: introduce a helper to modify hostflags
Date: Wed, 11 Mar 2020 18:20:06 +0100	[thread overview]
Message-ID: <20200311172010.7777-2-roger.pau@citrix.com> (raw)
In-Reply-To: <20200311172010.7777-1-roger.pau@citrix.com>

Add a generic function to perform database changes related to a host
flag and add a wrapper to TestSupport.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>
---
Changes since v4:
 - Move addition of hostflag_putative_record to a different patch.
 - Introduce a single helper in TestSupport: modify_host_flag.

Changes since v3:
 - Introduce modify_flag instead of {set/remove}_flag.
 - Introduce a generic modify_host helper.
 - Split from patch 1.

17:08:58 Diziet royger: I think your ts-examine-hostprops-save hunk in 2/ belongs in 1/ ?  (Or in
                a separate 1.5/ along with hostflag_putative_record.)
