ocfs2/dlm: Target node death during resource migration leads to thread spin
During resource migration, if the target node were to die, the thread doing the migration spins until the target node is not removed from the domain map. This patch slows the spin by making the thread wait for the recovery to kick in. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Joel Becker <jlbec@evilplan.org>
