Subject: [PATCH] delayacct: cleanup flags in struct task_delay_info and functions use it
Date: Wed, 24 Nov 2021 07:00:00 +0000	[thread overview]
Message-ID: <20211124065958.36703-1-yang.yang29@zte.com.cn> (raw)

From: Yang Yang <yang.yang29@zte.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.
