compat: fix compile breakage on s390

2012-03-12T17:32:38+00:00

commit 048cd4e51d24ebf7f3552226d03c769d6ad91658 upstream.

The new is_compat_task() define for the !COMPAT case in
include/linux/compat.h conflicts with a similar define in
arch/s390/include/asm/compat.h.

This is the minimal patch which fixes the build issues.

[S390] dasd: check sense type in device change handler

2011-04-20T08:15:44+00:00

When evaluating sense data in dasd_eckd_check_for_device_change, we
must always check for the type of sense data in byte 27, bit 0, to
make sure that the rest of the sense data is interpreted correctly.

[S390] dasd: Add support for raw ECKD access.

2011-01-05T11:47:30+00:00

Normal I/O operations through the DASD device driver give only access
to the data fields of an ECKD device even for track based I/O.
This patch extends the DASD device driver to give access to whole
ECKD tracks including count, key and data fields.

[S390] dasd: Improve handling of stolen DASD reservation

2011-01-05T11:47:30+00:00

If a DASD device has been reserved by a Linux system, and later
this reservation is ‘stolen’ by a second system by means of an
unconditional reserve, then the first system receives a
notification about this fact. With this patch such an event can
be either ignored, as before, or it can be used to let the device
fail all I/O request, so that the device will not block anymore.
