Subject: [PATCH net v2] selftests: netfilter: conntrack_dump_flush: remove unused variables and fix typo
Date: Fri,  7 Aug 2026 15:59:28 +0800	[thread overview]
Message-ID: <20260807075928.64326-1-fffsqian@163.com> (raw)

From: Qingshuang Fu <fuqingshuang@kylinos.cn>

Remove unused 'rplnlh' in conntrack_data_insert(), and remove unused
'rplnlh' and 'nest' variables in conntrack_count_zone() and
conntrack_flush_zone(). These variables were declared but never used
since their introduction.

Also fix typo: rename misspelled conntracK_count_zone() to
conntrack_count_zone().

v2:
  - Drop Fixes tag as this is a cleanup, not a bug fix
  - Add Reviewed-by tag from Fernando Fernandez Mancera
  - Also fix the typo in function name conntracK_count_zone
  - Link to v1: https://lore.kernel.org/all/20260806075052.1934904-1-fffsqian@163.com/
