Hi,
We detected below error messages in fio pmem test for btrfs.
machine: Intel(R) Xeon(R) CPU E5-2695 v3 @ 2.30GHz with 256G memory
kernel: v4.10
test parameters:
[global]
bs=2M
ioengine=mmap
iodepth=32
size=7669584457
direct=0
runtime=200
invalidate=1
fallocate=posix
group_reporting
time_based
[task_0]
rw=write
directory=/fs/pmem0
numjobs=14
[task_1]
rw=write
directory=/fs/pmem1
numjobs=14
==> /tmp/stderr <==
fio: pid=2214, got signal=7

fio: pid=2213, got signal=7
fio: pid=2202, got signal=7
fio: pid=2206, got signal=7
fio: pid=2207, got signal=7
fio: file hash not empty on exit
while fio test is ok for ext4 with the same test parameters.
Attached reproduce.sh may help reproduce the problem.
Thanks,

Attach kmsg and reproduce script.
Note: kernel cmdline contained "memmap=104G!4G memmap=104G!132G"
