[PATCH] btrfs: don't trigger autodefrag if cleaner is woken up early

by Qu Wenruo

[PROBLEM] Patch "btrfs: don't let new writes to trigger autodefrag on the same inode" now makes autodefrag really only to scan one inode once per autodefrag run. That patch works mostly fine, as the trace events show their intervals are almost 30s: (only showing the root 257 ino 329891 start 0) 486.810041: defrag_file_start: root=257 ino=329891 start=0 len=754728960 506.407089: defrag_file_start: root=257 ino=329891 start=0 len=754728960 536.463320: defrag_file_start: root=257 ino=329891 start=0 len=754728960 539.721309: defrag_file_start: root=257 ino=329891 start=0 len=754728960 569.741417: defrag_file_start: root=257 ino=329891 start=0 len=754728960 594.832649: defrag_file_start: root=257 ino=329891 start=0 len=754728960 624.258214: defrag_file_start: root=257 ino=329891 start=0 len=754728960 654.856264: defrag_file_start: root=257 ino=329891 start=0 len=754728960 684.943029: defrag_file_start: root=257 ino=329891 start=0 len=754728960 715.288662: defrag_file_start: root=257 ino=329891 start=0 len=754728960 But there are some outlawers, like 536s->539s, it's only 3s, not the 30s default commit interval. [CAUSE] There are several call sites which can wake up transaction kthread early, while transaction kthread itself can skip transaction if its timer doesn't reach commit interval, but cleaner is always woken up. This means each time transaction ktreahd gets woken up, we also trigger autodefrag, even transaction kthread chooses to skip its work. This is not a good behavior for files under heavy write load, as we waste extra IO/CPU while the defragged extents can easily get fragmented again. [FIX] In btrfs_run_defrag_inodes(), we check if our current time is larger than last run + commit_interval. If not, skip this run and wait for next opportunity. This patch along with patch "btrfs: don't let new writes to trigger autodefrag on the same inode" are mostly for backport to v5.16. This is just to reduce the unnecessary IO/CPU caused by autodefrag, the final solution would be allowing users to change autodefrag scan interval and target extent size.

Re: laptop does not go to suspend anymore with kernel version > 5.16.10

Can you please enlighten me about that? I have no idea, I'm just tracking regressions and sadly don't known much about this. To me it looks a bit like s2idle is not working properly, but I might be totally wrong with that. Maybe google might tell you; or some measurements where you check how quickly the batter drains in sleep. Oof you ask the PM developers -- but as this is not a regression neither the regressions list nor the stable list care, so I guess you do it in a separate mail. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. > Am Mittwoch, dem 09.03.2022 um 07:51 +0100 schrieb Thorsten Leemhuis: >> Hi! >> >> On 08.03.22 19:21, Reinhold Mannsberger wrote: >>> >>> I am using Linux Mint Xfce 20.3 with kernel version 5.16.

kernel BUG at include/linux/swapops.h:204!

Hi Linux kernel team, We have had multiple servers lock up over the course of a few months on kernel version 5.10.92 Looking to find out any information to help mitigate this. I've also found a related report here back in 2021: https://lore.kernel.org/all/757b684a-67b5-999b-7f2d-b55fb1c61fd8@google.com… Please see the stack trace obtained during this lockup [2136172.975892] ------------[ cut here ]------------ [2136172.975896] kernel BUG at include\/linux\/swapops.h:204!
