It seems that it's the log flags, not priority, and currently this is
the intended output:
$ crash -h log
-m Display the message log level in brackets preceding each message. For
the variable-length record format, the level will be displayed in
hexadecimal, and depending upon the kernel version, also contains the
facility or flags bits.
But I'm fine with this change, because crash shows only the log level on
5.10+ kernels again and I think the flags is not often needed for analysis
and the flags/level value can be shown by "set debug 1" if needed.
So could you modify also the help description and commit message?
Thanks,
Kazu
