calc_lcoefs

Name:Take the followings as input*@bps maximum sequential throughput*@seqiops maximum sequential 4k iops*@randiops maximum random 4k iops* and calculate the linear model cost coefficients

Proto:static void calc_lcoefs(u64 bps, u64 seqiops, u64 randiops, u64 *page, u64 *seqio, u64 *randio)

Type:void

Parameter:

Type	Parameter	Name
u64	bps
u64	seqiops
u64	randiops
u64 *	page
u64 *	seqio
u64 *	randio

786

page = seqio = randio = 0

788

If bps Then page = DIV64_U64_ROUND_UP(VTIME_PER_SEC, DIV_ROUND_UP_ULL(bps, IOC_PAGE_SIZE))

792

If seqiops Then

793

v = DIV64_U64_ROUND_UP(VTIME_PER_SEC, seqiops)

794

If v > page Then seqio = v - page

798

If randiops Then

799

v = DIV64_U64_ROUND_UP(VTIME_PER_SEC, randiops)

800

If v > page Then randio = v - page
