Subject: [PATCH v20210713 04/31] xl: fix description of migrate --debug
Date: Tue, 13 Jul 2021 20:05:38 +0200	[thread overview]
Message-ID: <20210713180605.12096-5-olaf@aepfle.de> (raw)
In-Reply-To: <20210713180605.12096-1-olaf@aepfle.de>

xl migrate --debug used to track every pfn in every batch of pages.
But these times are gone. The code in xc_domain_save is the consumer
of this knob, now may enable verification mode.

Signed-off-by: Olaf Hering <olaf@aepfle.de>

v03:
- adjust to describe what --debug would do when the code which
  consumes this knob is fixed.
v02:
- the option has no effect anymore
