Subject: [linus:master] [blk]  4e63aeb5d0:  swapin.throughput -76.7%
 regression



Hello,

kernel test robot noticed a -76.7% regression of swapin.throughput on:


commit: 4e63aeb5d0101ddada36a2f64f048e2f9d2202fc ("blk-wbt: don't throttle swap writes in direct reclaim")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

testcase: swapin
test machine: 4 threads 1 sockets Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz (Ivy Bridge) with 8G memory
parameters:

	disk: 1HDD
	size: 8G
	nr_task: 72
	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
| Reported-by: kernel test robot <oliver.sang@...el.com>
| Closes: https://lore.kernel.org/oe-lkp/202408061623.ed5cd480-oliver.sang@intel.com
