bfq_timeout_sync_store

Name:Leaving this name to preserve name compatibility with cfq* parameters, but this timeout is used for both sync and async.

Proto:static ssize_t bfq_timeout_sync_store(struct elevator_queue *e, const char *page, size_t count)

Type:ssize_t

Parameter:

Type	Parameter	Name
struct elevator_queue *	e
const char *	page
size_t	count

6700

bfqd = elevator_data

6704

ret = bfq_var_store( & __data, (page))

6705

If ret Then Return ret

6708

If __data < 1 Then __data = 1

6710

Else if __data > INT_MAX Then __data = INT_MAX

* Timeout for bfq_queues to consume their budget; used to * prevent seeky queues from imposing long latencies to * sequential or quasi-sequential ones (this also implies that * seeky queues cannot receive guarantees in the service * domain; after a timeout = msecs_to_jiffies: - convert milliseconds to jiffies*@m: time in milliseconds* conversion is done as follows:* - negative values mean 'infinite timeout' (MAX_JIFFY_OFFSET)* - 'too large' values [that would result in larger than

If user-configured max budget value (0 for auto-tuning) == 0 Then maximum budget allotted to a bfq_queue before rescheduling = In autotuning mode, max_budget is dynamically recomputed as the* amount of sectors transferred in timeout at the estimated peak* rate. This enables BFQ to utilize a full timeslice with a full* budget, even if the in-service queue is served at peak rate
