This patch set is a working POC how to reduce mess with partially printed lines. In addition, it fixes some races when replying logbuffer on new consoles.
It can be applied on top of v12 of the async printk patches, see https://lkml.kernel.org/g/20160513131848.2087-1-sergey.senozhat...@gmail.com But it is basically independent on the async printk stuff. I wanted to see how my proposal could look like in practice https://lkml.kernel.org/g/20160712162809.ge32...@pathway.suse.cz IMPORTANT: I have vacation next two weeks and will not have much access to the newtwork. I wanted to sent what I had before leaving. The last patch is not much tested. Feel free to take it, rework it yourself or just send your opinion.
