Series [net-next,1/7] netconsole: prefix CPU_NR sysdata feature with SYSDATA_ | expand

Commit Message

New SYSDATA_TASKNAME feature flag to track when taskname append is enabled.

Additional check in count_extradata_entries() to include taskname in
total, counting it as an entry in extradata. This function is used to
check if we are not overflowing the number of extradata items.
