The patch titled Subject: delayacct: cleanup flags in struct task_delay_info and functions use it has been added to the -mm tree. Its filename is delayacct-cleanup-flags-in-struct-task_delay_info-and-functions-use-it.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/delayacct-cleanup-flags-in-struct-task_delay_info-and-functions-use-it.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/delayacct-cleanup-flags-in-struct-task_delay_info-and-functions-use-it.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Yang Yang <yang.yang29@xxxxxxxxxx> Subject: delayacct: cleanup flags in struct task_delay_info and functions use it 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 their own functions.
