[btrfs] 8d47a0d8f7: fio.write_bw_MBps -28.6% regression

by kernel test robot

Greeting, FYI, we noticed a -28.6% regression of fio.write_bw_MBps due to commit: commit: 8d47a0d8f7947422dd359ac8e462687f81a7a137 ("btrfs: Do mandatory tree block check before submitting bio")

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master commit fcc784be837714a9173b372ff9fb9b514590dad9 Author: Steven Rostedt (VMware) <rostedt(a)goodmis.org> AuthorDate: Wed Apr 4 14:06:30 2018 -0400 Commit: Ingo Molnar <mingo(a)kernel.org> CommitDate: Thu Jun 21 18:19:01 2018 +0200 locking/lockdep: Do not record IRQ state within lockdep code While debugging where things were going wrong with mapping enabling/disabling interrupts with the lockdep state and actual real enabling and disabling interrupts, I had to silent the IRQ disabling/enabling in debug_check_no_locks_freed() because it was always showing up as it was called before the splat was. Use raw_local_irq_save/restore() for not only debug_check_no_locks_freed() but for all internal lockdep functions, as they hide useful information about where interrupts were used incorrectly last.

Greeting, FYI, we noticed a -16.5% regression of vm-scalability.median due to commit: commit: 7d43f1ce9dd075d8b2aa3ad1f3970ef386a5c358 ("locking/rwsem: Enable time-based spinning on reader-owned
