Subject: [lkp] [NFSv4] 931437ee2c: BUG: sleeping function called from
invalid context at mm/slab.h:393
FYI, we noticed the following commit:
https://github.com/0day-ci/linux Sebastian-Andrzej-Siewior/NFSv4-replace-seqcount_t-with-a-seqlock_t/20161022-013104
commit 931437ee2c100a50c36771c947ce3674f8160592 ("NFSv4: replace seqcount_t with a seqlock_t")
in testcase: ebizzy
with following parameters:
nr_threads: 200%
iterations: 100x
duration: 10s
ebizzy is designed to generate a workload resembling common web application server workloads.
on test machine: qemu-system-x86_64 -enable-kvm -cpu kvm64,+ssse3 -m 1G
