Proto:static u64 iolatency_prfill_limit(struct seq_file *sf, struct blkg_policy_data *pd, int off)

Type:u64

Parameter:

TypeParameterName
struct seq_file *sf
struct blkg_policy_data *pd
intoff
870  iolat = pd_to_lat(pd)
871  dname = blkg_dev_name(he blkg and policy id this per-policy data belongs to )
873  If Not dname || Not min_lat_nsec Then Return 0
875  seq_printf(sf, "%s target=%llu\n", dname, div_u64 - unsigned 64bit divide with 32bit divisor*@dividend: unsigned 64bit dividend*@divisor: unsigned 32bit divisor* This is the most common 64bit divide and should be used if possible,* as many 32bit archs can optimize this variant better than a full )
877  Return 0
