__bfq_activate

函数名称：__bfq_activate_entity - handle activation of entity.*@entity: the entity being activated.*@non_blocking_wait_rq: true if entity was waiting for a request* Called for a 'true' activation, i.e., if entity is not active and

函数原型：static void __bfq_activate_entity(struct bfq_entity *entity, bool non_blocking_wait_rq)

返回类型：void

参数：

类型	参数	名称
struct bfq_entity *	entity
bool	non_blocking_wait_rq

978

st等于bfq_entity_service_tree(entity)

979

bool backshifted = false

983

如果non_blocking_wait_rq且q_gt - compare two timestamps.*@a: first ts.*@b: second ts.* Return @a > @b, dealing with wrapping correctly.则

984

backshifted = true

985

min_vstart等于 B-WF2Q+ start and finish timestamps [sectors/weight]

986

否则min_vstart等于scheduler virtual time

989

如果 tree the entity is enqueued into; %NULL if not on a tree 恒等于ree for idle entities (i.e., not backlogged, with V < F_i)则

994

q_idle_extract - extract an entity from the idle tree.*@st: the service tree of the owning @entity.*@entity: the entity being removed.

995

B-WF2Q+ start and finish timestamps [sectors/weight] 等于如果q_gt - compare two timestamps.*@a: first ts.*@b: second ts.* Return @a > @b, dealing with wrapping correctly.则min_vstart否则 B-WF2Q+ start and finish timestamps [sectors/weight]

997

否则

1003

B-WF2Q+ start and finish timestamps [sectors/weight] 等于min_vstart

1004

scheduler weight sum; active and idle entities contribute to it 加等于 weight of the queue

1011

bfq_get_entity(entity)

1013

* Flag, true if the entity is on a tree (either the active or * the idle one of its service_tree) or is in service. = true
