Subject: [PATCH v6 2/3] livepatch: move transition "complete" notice into klp_complete_transition()
Date: Fri, 13 Oct 2017 15:08:42 -0400	[thread overview]
Message-ID: <1507921723-1996-3-git-send-email-joe.lawrence@redhat.com> (raw)
In-Reply-To: <1507921723-1996-1-git-send-email-joe.lawrence@redhat.com>

klp_complete_transition() performs a bit of housework before a
transition to KLP_PATCHED or KLP_UNPATCHED is actually completed
(including post-(un)patch callbacks).  To be consistent, move the
transition "complete" kernel log notice out of
klp_try_complete_transition() and into klp_complete_transition().
