Subject: [PATCH] delayacct: cleanup flags in struct task_delay_info and functions use it
From: Yang Yang <yang.yang29@....com.cn>
Flags in struct task_delay_info is used to distinguish the difference
between swapin and blkio delay acountings. But after patch "delayacct:
support swapin delay accounting for swapping without blkio", there is
no need to do that since swapin and blkio delay accounting use it's
own functions.
