Both in one, it reduces code churn. With pr_* + pr_fmt, the module name will be prefixed automatically, see e.g. commit e016c5e43db51875c2b541b59bd217494d213174 as an example. > > This would also probably allows us to save the line break in the error > > message, which IIRC is not a good practise either, eg. > > > > pr_warn("nf_queue: OOM " > > "in mangle, dropping packet\n"); > > > > > Perhaps coalesce the formats and remove the unnecessary periods too. The above message should be removed, its useless (on oom allocator already warns).

I think adding pr_fmt and use pr_() belongs to the same logical change, so one patch for this is fine. Thanks Arushi. P.S: Please, just send your patch netfilter-de...@vger.kernel.org next time, no need to Cc every list. Thanks!

I think Arushi could add pr_fmt in the same go, so we skip another follow up patch for this. @Arushi: I suggested this in my previous email, please have a look. This would also probably allows us to save the line break in the error message, which IIRC is not a good practise either, eg. pr_warn("nf_queue: OOM " "in mangle, dropping packet\n"); > Perhaps coalesce the formats and remove the unnecessary periods too. Yes, removing periods seems fine. Thanks.

[PATCH v2] net: netfilter: Replace printk() with appropriate pr_*() macro
Using pr_() is more concise than printk(KERN_). Replace printks having a log level with the appropriate pr_*() macros.
