Message-Id: <1927b7286ac7a14345708f810796c09337ea389a.1586496687.git.joe@perches.com>
Date: Thu, 9 Apr 2020 22:34:03 -0700
From: Joe Perches <joe@...ches.com>
To: Coly Li <colyli@...e.de>,
Kent Overstreet <kent.overstreet@...il.com>,
Shenghui Wang <shhuiw@...mail.com>,
Jens Axboe <axboe@...nel.dk>
Cc: Christophe JAILLET <christophe.jaillet@...adoo.fr>,
linux-bcache@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH] bcache: Convert pr_<level> uses to a more typical style
Remove the trailing newline from the define of pr_fmt and add newlines
to the uses.
Miscellanea:
o Convert bch_bkey_dump from multiple uses of pr_err to pr_cont
as the earlier conversion was inappropriate done causing multiple
lines to be emitted where only a single output line was desired
o Use vsprintf extension %pV in bch_cache_set_error to avoid multiple
line output where only a single line output was desired
o Coalesce formats
Fixes: 6ae63e3501c4 ("bcache: replace printk() by pr_*() routines")
Signed-off-by: Joe Perches <joe@...ches.com>
