Message-ID: <20241025130322.3077455-1-costa.shul@redhat.com> Date: Fri, 25 Oct 2024 16:03:16 +0300 From: Costa Shulyupin <costa.shul@...hat.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Wei Yang <richard.weiyang@...il.com>, Costa Shulyupin <costa.shul@...hat.com>, Steven Rostedt <rostedt@...dmis.org>, "Peter Zijlstra (Intel)" <peterz@...radead.org>, René Nyffenegger <mail@...enyffenegger.ch>, linux-kernel@...r.kernel.org Subject: [PATCH] scripts/tags.sh: Fix warnings "null expansion of name pattern" Warnings such as ctags: Warning: include/linux/wait_bit.h:59: null expansion of name pattern "\1" are triggered when parsing DECLARE_BITMAP() inside comments, resulting in an empty token. To avoid this, ensure only non-empty tokens.
