commit: e86ee2d44b44056243da17c120ad258717cedf9b ("ipmi: Rework locking and shutdown for hot remove")
https://github.com/cminyard/linux-ipmi master-ipmi-rebase
in testcase: vm-scalability
with following parameters:
runtime: 300
thp_enabled: never
thp_defrag: always
nr_task: 32
nr_pmem: 1
test: swap-w-rand
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
