Subject: [PATCH] fs/buffer: Remove the initialization of variables bh_{accounting, lrus}
Date: Sat, 18 Apr 2020 00:20:37 +0800 [thread overview]
Message-ID: <20200417162037.91546-1-pilgrimtao@gmail.com> (raw)
The static global variables will be automatically initialized to 0,
and we do not need to manually initialize to 0. So remove the
initialization of variable bh_{accounting, lrus}.
