Function Documentation

m0_fom_enthrall()

M0_INTERNAL void m0_fom_enthrall	(	struct m0_fom *	leader,
		struct m0_fom *	serf,
		struct m0_fom_thralldom *	thrall,
		void(*)(struct m0_fom_thralldom *thrall, struct m0_fom *serf)	end
	)

Arranges for the leader to be woken up once the serf reaches M0_FOM_PHASE_FINISH, should be called by leader fom. It is up to the caller to make sure the serf is actually executing and that the leader goes to sleep.

Note

It is not required to initialise thrall context before call, all context preparation is done inside of this function.
