[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] add PAV support to the dasd driver.

2006-06-29T13:08:18Z

Add support for parallel-access-volumes to the dasd driver. This allows concurrent access to dasd devices with multiple channel programs. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[S390] dasd whitespace and other cosmetics.

2006-06-29T12:58:12Z

Dasd code cleanup: 1) remove white space, 2) remove the emacs override sections, and 3) use kzalloc instead of kmalloc. Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky

[PATCH] s390: dasd device identifiers

2006-04-28T15:33:48Z

Generate new sysfs-attribute 'uid' that contains an device specific unique identifier. This can be used to identity multiple ALIASES of the same physical device (PAV). In addition the sysfs-attributes 'vendor' (containing the manufacturer of the device) and 'alias' (identify alias or base device) is added. This is first part of PAV support in LPAR (also valid on zVM). Signed-off-by: Horst Hummel Signed-off-by: Martin Schwidefsky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

BUG_ON() Conversion in drivers/s390/block/dasd_devmap.c

2006-03-26T16:33:07Z

this changes if() BUG(); constructs to BUG_ON() which is cleaner, contains unlikely() and can better optimized away. Signed-off-by: Eric Sesterhenn Signed-off-by: Adrian Bunk
