1069  如果非exclusive则
1070  ctrl_b等于shareable_bits
1071  如果bitmap_intersects( & cbm, & ctrl_b, cbm_len)则返回:true
1076  ctrl等于ctrl_val
1077  以i小于closids_supported()循环
1078  ctrl_b等于ctrl
1079  mode等于dtgroup_mode_by_closid - Return mode of resource group with closid*@closid: closid if the resource group* Each resource group is associated with a @closid
1080  如果losid_allocated - test if provided closid is in use*@closid: closid to be tested* Return: true if @closid is currently associated with a resource group,* false if @closid is free且i不等于closid且mode不等于RDT_MODE_PSEUDO_LOCKSETUP则
1082  如果bitmap_intersects( & cbm, & ctrl_b, cbm_len)则
1083  如果exclusive则
1084  如果mode恒等于RDT_MODE_EXCLUSIVE则返回:true
1086  继续下一循环
1088  返回:true
1093  返回:false
