From fc2d5988b5972bced859944986fb36d902ac3698 Mon Sep 17 00:00:00 2001 From: Coly Li Date: Sat, 11 Aug 2018 13:19:46 +0800 Subject: [PATCH] bcache: add identifier names to arguments of function definitions There are many function definitions do not have identifier argument names, scripts/checkpatch.pl complains warnings like this, WARNING: function definition argument 'struct bcache_device *' should also have an identifier name #16735: FILE: writeback.h:120: +void bch_sectors_dirty_init(struct bcache_device *); This patch adds identifier argument names to all bcache function definitions to fix such warnings.
