logbuf_lock. By moving things around a little, the console_sem can be
released without ever holding the logbuf_lock, and we can safely have
printk_sched() use the printk buffer directly.

Hello,
This is the next iteration of my printk patchset. Since v5 I've made the
limit for printing configurable via kernel parameter and let it default to 0.
So unless user sets printk.offload_chars on kernel command line, there will
be no difference to current printk behavior.

which limit to pick... If using fixed strings won't work out, using a limit
like 100 sectors would probably be the next best solution for me.

Just the reasoning in the changelog doesn't look completely correct - we
are free to succeed doing write to a FMODE_WRITE file descriptor even if
the filesystem below it decided to declare game

Hello,
this is another piece of the printk softlockup saga series. Let me first
remind the problem:
Currently, console_unlock() prints messages from kernel printk buffer to
console while the buffer is non-empty. When serial console is attached,
printing is slow and thus other CPUs in the
