[PATCH] s390: dasd proc interface typo

2006-03-10T03:47:38+00:00

[PATCH] s390: dasd partition detection

2006-03-08T22:14:01+00:00

DASD allows to open a device as soon as gendisk is registered, which means the device is a fake device (capacity=0) and we do know nothing about blocksize and partitions at that point of time. In case the device is opened by someone, the bdev and inode creation is done with the fake device info and the following partition detection code is just using the wrong data. To avoid this modify the DASD state machine to make sure that the open is rejected until the device analysis is either finished or an unformatted device was detected.

[PATCH] s390: revert dasd eer module

2006-02-21T04:00:12+00:00

Revert dasd eer module until we have a common understanding of how the interface should be. Signed-off-by: Heiko Carstens Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] s390: dasd reference counting

2006-02-21T04:00:12+00:00

When using the dasd diag discipline, the base discipline module (eckd or fba) can be unloaded, even though the dasd driver requires both discipline modules (base and diag) to work correctly. Implement reference counting for both base and diag discipline modules in order to fix this.

[PATCH] s390: dasd extended error reporting module

2006-02-03T16:32:01+00:00

The DASD extended error reporting is a facility that allows to get detailed information about certain problems in the DASD I/O. This information can be used to implement fail-over applications that can recover these problems.

[PATCH] s390: dasd wait for clear i/o interrupt

2006-02-01T16:53:24+00:00

The sleep_on function clears a running cqr without waiting for the related interrupt. This can lead to a panic at the time the interrupt is processed because the related memory might already be freed. Wait for clear-interrupt and de-queue cqr prior to return.

[PATCH] s390: dasd open counter

2006-02-01T16:53:24+00:00

The open_count is increased for every opener, that includes the blkdev_get in dasd_scan_partitions. This tampers the open_count in BIODASDINFO. Hide the internal open from user-space.

[PATCH] s390: Remove CVS generated information

2006-02-01T16:53:23+00:00

- Remove all CVS generated information like e.g. revision IDs from drivers/s390 and include/asm-s390 (none present in arch/s390). - Add newline at end of arch/s390/lib/Makefile to avoid diff message.

[PATCH] s390: fix blk_queue_ordered call in dasd.c fixup

2006-01-15T02:27:10+00:00

The QUEUE_ORDERED_* numbers got renumbered and by accident the dasd driver was changed to use QUEUE_ORDERED_DRAIN instead of QUEUE_ORDERED_TAG. Signed-off-by: Heiko Carstens Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] s390: fix blk_queue_ordered call in dasdc

2006-01-15T02:27:09+00:00

Add the missing third argument to the blk_queue_ordered call and use the constant QUEUE_ORDERED_DRAIN instead of "1". Signed-off-by: Martin Schwidefsky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
