Reviewed-by: Pasha Tatashin <[email protected]> A comment in FLB patch would also need to be updated: 633 * Context: Called from liveupdate_reboot() just before kho_finalize(). 634 */ 635 void luo_flb_serialize(void) But, given that patch has not yet landed, it should be updated separately, as it is likely this work lands first.
