Message-Id: <d67377660a317c826a7899e6ffcb5bf686733ddb.1597615399.git.joe@perches.com>
Date: Sun, 16 Aug 2020 15:04:52 -0700
From: Joe Perches <joe@...ches.com>
To: Jeff Layton <jlayton@...nel.org>, Ilya Dryomov <idryomov@...il.com>
Cc: ceph-devel@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 1/2] ceph: Use generic debugging facility
The dout macro duplicates the generic features of pr_debug with
__FILE__ and __func__ output capability when using dynamic_debug.
Convert dout to pr_debug and remove the "pretty" print feature
of dout.
Miscellanea:
o Realign arguments
