Hi,
this was inspired by recent Anand's post to change the printing format of the
btrfs_err etc. helpers to include UUID. We do not use the helpers everywhere,
so I've introduced all the missing variants that require eg printing the
rcu_string (device name), are ratelimited or are both ratelimited and using
rcu_string.
First part introduces macros and switches existing users, the patch 7/7 converts
some printks to the helpers (avoiding mostly debugging messages).
In the end we should route all user-visile messages through some common
formatter, this is preparatory work. The mount-time messages are still
printk-based.
Please consider for the 4.4 dev cycle. Thanks.
