NOTE:
While running LTP containers test suite,
I noticed this kernel panic on arm64 Juno-r2 devices.
Not easily reproducible and not seen on any other arm64 devices.

steps to reproduce:
---------------------------
# boot stable rc 5.4.70 kernel on juno-r2 machine
# cd /opt/ltp
# ./runltp -f containers

Crash log,
---------------
pidns13     0  TINFO  :  cinit2: writing some data in pipe
pidns13     0  TINFO  :  cinit1: setup handler for async I/O on pipe
pidns13     1  TPASS  :  cinit1: si_fd is 6, si_code is 1
