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.senozhatsky@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.GE32373@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. Petr Mladek (4): printk: Prepeparation for fake cont buffers printk: Do not block cont buffer by partially flushed lines printk: Flush the cont buffer after the other lines printk: Correctly replay buffer log for a new console kernel/printk/printk.c | 235 +++++++++++++++++++++++++++---------------------- 1 file changed, 128 insertions(+), 107 deletions(-) -- 1.8.5.6
