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
