[S390] dasd PAV enabling.

2006-08-24T11:22:36Z

The subsystem check in the PAV code is incorrect, it enables PAV per device instead of per subsystem. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[S390] inaccessible PAV alias devices on LPAR.

2006-08-16T11:49:33Z

In some situations PAV alias devices on LPAR are not accessible. The initialization procedure required to enable access to PAV alias devices has to be performed per storage server subsystem and not only once per storage server. Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky

[S390] dasd slab cache alignment.

2006-08-16T11:49:27Z

The dasd_page_cache should return page addresses and therefore the cache must be created with an alignment of PAGE_SIZE. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] dasd calls kzalloc while holding a spinlock.

2006-08-10T13:45:16Z

The dasd function dasd_set_uid calls kzalloc while holding the dasd_devmap_lock. Rearrange the code to do the memory allocation outside the lock. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[S390] dasd set offline kernel bug.

2006-08-09T08:30:22Z

The request queue flush function of the dasd driver has to dequeue the requests first and then call the end request function. Otherwise a kernel bug in ll_rw_block.c might get triggered. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[S390] xpram system device class.

2006-08-07T16:13:06Z

Remove system device class for xpram. It creates the directory hierarchy under /sys/devices/system/xpram/xpram0. The xpram0 directory is empty and it is always created while xpram1 and following devices are always missing, independent if the devices exist or not. Since the xpram devices are listed in /proc/partitions and /sys/block/ as slram the system device class for xpram is meaningless. Signed-off-by: Martin Schwidefsky

[S390] xpram module parameter parsing - take 2.

2006-07-17T14:09:23Z

Don't use memparse since the default size modifier is 'k'. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] xpram module parameter parsing.

2006-07-12T14:40:14Z

The module parameters for xpram are not or in a wrong way parsed. The xpram module uses the module_param_array directive with an int parameter which causes the kernel to automatically parse the passed numbers. This will cause errors if arguments are omitted or cause wrong results if arguments have size qualifiers. Use module_param_array with charp and parse the arguments later.
