Remove the tape block device driver. It's not of real use but has
already created some confusion when users wanted to access tape devices
and used the block device nodes instead of the character device nodes.Also remove the whole tape documentation since it's completely outdated
and we have the device drivers book which is the place where everything
is properly documented.Signed-off-by: Heiko Carstens

In ccw_device_set_online we basically start path verification and
wait for the device to reach a final state. If it turns out that the
device has no useable path we schedule the deregistration of the
device (which is still in an non-final state) and wake up the waiting
process. The deregistration process will set a final state, but if
the wake up happens to be prior to this, the device will hang forever
in ccw_device_set_online.To fix this just set the final NOT_OPER state prior to the scheduled
deregistration of the device.Signed-off-by: Sebastian Ott

pfault, dasd diag and virtio all use the same external interrupt number.
The respective interrupt handlers decide by the subcode if they are
meant to handle the interrupt.
Counting is currently done before looking at the subcode which means
each handler counts an interrupt even if it is not handling it.
Fix this by moving the kstat code after the code which looks at the
subcode.Signed-off-by: Heiko Carstens

In-kernel disk event polling doesn't matter for legacy/fringe drivers
and may lead to infinite event loop if ->check_events() implementation
generates events on level condition instead of edge.Now that block layer supports suppressing exporting unlisted events,
simply leaving disk->events cleared allows these drivers to keep the
internal revalidation behavior intact while avoiding weird
interactions with userland event handler.Signed-off-by: Tejun Heo

The qdio hardware may surpress further interrupts as long as a SBAL is in
the error state. That can lead to unnotified data in the SBALs following
the error state. To prevent this behaviour change the SBAL[s] in error
state immediately to another program owned state so interrupts are again
received for further traffic on the device.Signed-off-by: Jan Glauber

The dasd_open function uses the private_data pointer of the gendisk to
find the dasd_block structure that matches the gendisk. When a DASD
device is set offline, we set the private_data pointer of the gendisk
to NULL and later remove the dasd_block structure, but there is still
a small race window, in which dasd_open could first read a pointer
from the private_data field and then try to use it, after the structure
has already been freed.
To close this race window, we will store a pointer to the dasd_devmap
structure of the base device in the private_data field. The devmap
entries are not deleted, and we already have proper locking and
reference counting in place, so that we can safely get from a devmap
pointer to the dasd_device and dasd_block structures of the device.Signed-off-by: Stefan Weinhuber

The cio_ignore purge function is intended to only remove CCW devices
which are in the offline state. There is a time frame after the purge
function finished where a CCW device is scheduled for removal but
still accessible. When the device is set online during this time
frame, it may first appear online before it is then removed.Fix this by preventing that CCW devices can be set online while there
is work (such as removal triggered by the purge function) for it
pending. Also ensure that the purge function does not schedule devices
for removal which are in the process of being set online.Signed-off-by: Peter Oberparleiter
