Subject: [v4 09/11] Add durable_name_printk_ratelimited
Date: Fri, 24 Jul 2020 12:17:04 -0500
Message-ID: <20200724171706.1550403-10-tasleson@redhat.com> (raw)
In-Reply-To: <20200724171706.1550403-1-tasleson@redhat.com>

Create a rate limited macro for durable_name_printk so that
we can use this for printk_ratelimited usage in the block
layers and add the durable name key/value to the log
message.
