Subject: Re: [PATCH v11 5/9] Reimplement RLIMIT_MSGQUEUE on top of ucounts
Hi Alexey,
When lkp team run kernel selftests, we found after these series of patches, testcase mqueue: mq_perf_tests
in kselftest failed with following message.
If you confirm and fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot lkp@...el.com
```
# selftests: mqueue: mq_perf_tests
#
# Initial system state:
# Using queue path: /mq_perf_tests
# RLIMIT_MSGQUEUE(soft): 819200
# RLIMIT_MSGQUEUE(hard): 819200
# Maximum Message Size: 8192
# Maximum Queue Size: 10
# Nice value: 0
#
# Adjusted system state for testing:
# RLIMIT_MSGQUEUE(soft): (unlimited)
# RLIMIT_MSGQUEUE(hard): (unlimited)
# Maximum Message Size: 16777216
# Maximum Queue Size: 65530
# Nice value: -20
