[PATCH] s390: dasd device identifiers

2006-04-28T15:33:48+00:00

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).

[PATCH] s390: dasd ioctl never returns

2006-04-28T15:33:48+00:00

The dasd state machine is not designed to enable an unformatted device, since
'unformatted' is a final state.  The BIODASDENABLE ioctl calls
dasd_enable_device() which never returns if the device is in this special
state.  Return -EPERM in dasd_increase_state for unformatted devices to make
dasd_enable_device terminate.  Note: To get such an unformatted device online
it has to be re-analyzed.  This means that the device needs to be disabled
prior to re-enablement.

[PATCH] s390: dasd proc entries

2006-04-11T13:18:38+00:00

The proc_mkdir calls in the dasd driver are not check for NULL pointers.  Add
code to check the pointers and bail out if one of the proc entries could not
be created.

[PATCH] s390: fail-fast requests on quiesced devices

2006-04-11T13:18:38+00:00

Using the fail-fast flag in i/o requests on a dasd disk which has been
quiesced leads to kernel panics.  Modify the request start function to only
work on requests in a valid state.

[PATCH] s390: dasd device offline messages

2006-04-11T13:18:38+00:00

The dasd driver sometimes print the misleading message "Can't offline dasd
device with open count = 0".  The reason why it can't offline the device in
this case is that the device is still in the startup phase.  Print a more
meaningful message.

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

2006-03-31T23:27:08+00:00

this changes if() BUG(); constructs to BUG_ON() which is
cleaner, contains unlikely() and can better optimized away.

[PATCH] Remove MODULE_PARM

2006-03-25T16:22:52+00:00

MODULE_PARM was actually breaking: recent gcc version optimize them out as
unused.  It's time to replace the last users, which are generally in the
most unloved drivers anyway.
