The partial backport of the printk_deferred_enter/exit definitions looks fine to me. I am just not sure what is the preferred way of adding this to stable trees. Tetsuo merged the partial backport with the mm fix. Alternative solution would be to add the partial backport as a separate patch. Anyway, the commit message should mention the original commit 85e3e7fbbb720b9897f ("printk: remove NMI tracking"). Best Regards, Petr
