This isn't quite correct, since the VWC merely states if a potential
write back cache is volatile or not. But for the purpose of write
absortion, it's good enough.

If we're doing reclaim or sync IO, use WRITE_SYNC to inform the lower

This patchset isn't as much a final solution, as it's demonstration
of what I believe is a huge issue. Since the dawn of time, our
background buffered writeback has sucked. When we do background
buffered writeback, it should have little impact on foreground
activity. That's the definition of backgr
Avoid losing context by propagating the various reason why we
initiate writeback.

Add wbc_to_write(), which returns the write type to use, based on a

prepares us for factoring other wbc fields for write type.

Currently, printk() sometimes waits for message to be printed to console
and sometimes it does not (when console_sem is held by some other
process). In case printk() grabs console_sem and starts printing to
console, it prints messages from kernel printk buffer until the buffer
is e
ntage that printing always happens from a schedulable
context and thus we don't lockup any particular CPU or even interrupts.

Offload printing of scheduler deferred messages from IRQ context
to a schedulable printing kthread, when possible (the same way we
do it in vprintk_emit()). Otherwise, the CPU can spend unbounded
amount of time doing printing in console_unlock() from IRQ.

Hi,
Apparently I dropped the subject on this one, it's of course v2 of the
writeback not sucking patchset...
