Subject: [PATCH] mm: change "char *bdi_unknown_name" to "char bdi_unknown_name[]"
Date: Thu, 12 May 2022 22:48:29 +0800 [thread overview]
Message-ID: <20220512144829.5148-1-liqiong@nfschina.com> (raw)
In-Reply-To: <20220512082637.24649-1-liqiong@nfschina.com>
"char bdi_unknown_nam[]" string form declares a single variable.
It is better than "char *bdi_unknown_name" which creates two
variables.
