Hi
execute nvme testcase， some cases throw the same error info。
LOG：
nvme/007 (create an NVMeOF target with a file-backed ns) [failed]

Running nvme/007
+tests/nvme/rc: line 236: printf: write error: Invalid argument

this line is enable namespace。
CODE：
221 _create_nvmet_ns() {
222 local nvmet_subsystem="$1"
223 local nsid="$2"
224 local blkdev="$3"
225 local uuid="00000000-0000-0000-0000-000000000000"
226 local subsys_path="${NVMET_CFS}/subsystems/${nvmet_subsystem}"

229 if [[ $# -eq 4 ]]; then
230 uuid="$4"
231 fi
232
233 mkdir "${ns_path}"
234 printf "%s" "${blkdev}" > "${ns_path}/device_path"
235 printf "%s" "${uuid}" > "${ns_path}/device_uuid"
236 printf 1 > "${ns_path}/enable"
237 }
after check, enable the namespace should be with NVMe device.
Test(change device_path and reset enable):
root@lkp-knm01 /sys/kernel/config/nvmet/subsystems/blktests-subsystem-1/namespaces/1# cat device_path
/blktests/results/tmpdir.nvme.007.S8p/img

1
root@lkp-knm01 /sys/kernel/config/nvmet/subsystems/blktests-subsystem-1/namespaces/1#
so should remove L236 or change test device？
thanks and look forward to advice.
