Subject: [linux-next:master] [btrfs]  4591c3ef75:  fsmark.files_per_sec 6.0% regression
Date: Mon, 1 Dec 2025 15:13:06 +0800	[thread overview]
Message-ID: <202512011418.cce5b747-lkp@intel.com> (raw)



Hello,

kernel test robot noticed a 6.0% regression of fsmark.files_per_sec on:


commit: 4591c3ef751d861d7dd95ff4d2aadb1b5e95854e ("btrfs: make sure all btrfs_bio::end_io are called in task context")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

[still regression on linux-next/master 7d31f578f3230f3b7b33b0930b08f9afd8429817]

testcase: fsmark
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:

	iterations: 1x
	nr_threads: 1t
	disk: 1BRD_32G
	fs: btrfs
	filesize: 4K
	test_size: 4G
	sync_method: fsyncBeforeClose
	nr_files_per_directory: 1fpd
	cpufreq_governor: performance



If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
