[PATCH v8 4/3] content: Minor change to clarify free_page_hint_cmd_id

From: Alexander Duyck <>

The original wording was a bit unclear and could have been misinterpreted
as indicating that VIRTIO_BALLOON_FREE_PAGE_HINT was read-only instead of
the field free_page_hint_cmd_id. To clarify that break it up into two
sentences making it clear that the field is only available if the feature
is negotiated, and that the field is read-only.

Signed-off-by: Alexander Duyck <>

So this patch addresses a minor nit that was pointed out after the ballot
had already been created. If need be I can either open a new bugzilla and
request a ballot to have it added.
