[PATCH] direct-io: bug fix in dio handling write error
There is a bug in direct-io on propagating write error up to the higher I/O
layer. When performing an async ODIRECT write to a block device, if a
device error occurred (like media error or disk is pulled), the error code
is only propagated from device driver to the DIO layer. The error code
stops at finished_one_bio(). The aysnc write, however, is supposedly have
a corresponding AIO event with appropriate return code (in this case -EIO).
Application which waits on the async write event, will hang forever since
such AIO event is lost forever (if such app did not use the timeout option
in io_getevents call. Regardless, an AIO event is lost).
The discovery of above bug leads to another discovery of potential race
window with dio->result. The fundamental problem is that dio->result is
overloaded with dual use: an indicator of fall back path for partial dio
write, and an error indicator used in the I/O completion path. In the
event of device error, the setting of -EIO to dio->result clashes with
value used to track partial write that activates the fall back path.
It was also pointed out that it is impossible to use dio->result to track
partial write and at the same time to track error returned from device
driver. Because direct_io_work can only determines whether it is a partial
write at the end of io submission and in mid stream of those io submission,
a return code could be coming back from the driver. Thus messing up all
the subsequent logic.
Proposed fix is to separating out error code returned by the IO completion
path from partial IO submit tracking. A new variable is added to dio
structure specifically to track io error returned in the completion path.

Implement the half-closed devices notifiation, by adding a new POLLRDHUP
(and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the
existing POLLHUP handling, that does not report correctly half-closed
devices, was feared to be changed, this implementation leaves the current
POLLHUP reporting unchanged and simply add a new bit that is set in the few
places where it makes sense. The same thing was discussed and conceptually
agreed quite some time ago:
http://lkml.org/lkml/2003/7/12/116
Since this new event bit is added to the existing Linux poll infrastruture,
even the existing poll/select system calls will be able to use it. As far
as the existing POLLHUP handling, the patch leaves it as is. The
pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing
archs and sets the bit in the six relevant files. The other attached diff
is the simple change required to sys/epoll.h to add the EPOLLRDHUP
definition.
There is "a stupid program" to test POLLRDHUP delivery here:

[PATCH] IRQ: prevent enabling of previously disabled interrupt
This fix prevents re-disabling and enabling of a previously disabled
interrupt. On an SMP system with irq balancing enabled; If an interrupt is
disabled from within its own interrupt context with disable_irq_nosync and is
also earmarked for processor migration, the interrupt is blindly moved to the
other processor and enabled without regard for its current "enabled" state.
If there is an interrupt pending, it will unexpectedly invoke the irq handler
on the new irq owning processor (even though the irq was previously disabled)
The more intuitive fix would be to invoke disable_irq_nosync and
enable_irq, but since we already have the desc->lock from __do_IRQ, we
cannot call them directly. Instead we can use the same logic to disable
and enable found in disable_irq_nosync and enable_irq, with regards to the
desc->depth.
This now prevents a disabled interrupt from being re-disabled, and more
importantly prevents a disabled interrupt from being incorrectly enabled on
a different processor.

Remove the assumption that driver_register() returns the number of devices
bound to the driver. In fact, it returns zero for success or a negative
error value.
zorro_module_init() used the device count to automatically unregister and
unload drivers that found no devices. That might have worked at one time,
but has been broken for some time because zorro_register_driver() returned
either a negative error or a positive count (never zero). So it could only
unregister on failure, when it's not needed anyway.
This functionality could be resurrected in individual drivers by counting
devices in their .probe() methods.

[PATCH] initcall failure reporting
We presently ignore the return values from initcalls. But that can carry
useful debugging information. So print it out if it's non-zero.
It turns out the -ENODEV happens quite a lot, due to built-in drivers which
have no hardware to drive. So suppress that unless initcall_debug was
specified.
Also make the warning message more friendly by printing the name of the
initcall function.
Also drop the KERN_DEBUG from the initcall_debug message. If we specified
inticall_debug then we obviously want to see the messages.
