[Drbd-dev] [Patch v2 02/10] drbd: Add option zap_devices to new-current-uuid

[Philipp Reisner]

Hi Nick,

When introducing new fields alsways mark them as optional. Otherwise
a new kernel/module code would refuse netlink messages from older
drbd-utils:

> +	__flg_field(2, DRBD_GENLA_F_MANDATORY, zap_devices)

__flg_field(2, /* OPTIONAL */ 0, zap_devices)

best regards,
 Phil
