And remove the now unneeded number field. Also fixes all drivers that set these fields. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-05-20[SCSI] fix (unlikely) memory leak in DAC960 driverJesper Juhl1-6/+7
The Coverity checker found a memory leak (bug nr. 1245) in drivers/block/DAC960.c::DAC960_V2_ProcessCompletedCommand() The leak is pretty unlikely since it requires that the first of two successive kmalloc() calls fail while the second one succeeds. But it can still happen even if it's unlikely. If the first call that allocates 'PhysicalDeviceInfo' fails but the one that allocates 'InquiryUnitSerialNumber' succeeds, then we will leak the memory allocated to 'InquiryUnitSerialNumber' when the variable goes out of scope. A simple fix for this is to change the existing code that frees 'PhysicalDeviceInfo' if that one was allocated but 'InquiryUnitSerialNumber' was not, into a check for either pointer being NULL and if so just free both. This is safe since kfree() can deal with being passed a NULL pointer and it avoids the leak. While I was there I also removed the casts of the kmalloc() return value since it's pointless. I also updated the driver version since this patch changes the workings of the code (however slightly). This issue could probably be fixed a lot more elegantly, but the code is a big mess IMHO and I just took the least intrusive route to a fix that I could find instead of starting on a cleanup as well (that can come later).

2006-01-09[PATCH] drivers/block: Use ARRAY_SIZE macroTobias Klauser1-1/+1

2006-01-09[PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig1-21/+14
HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

2006-01-06[BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo1-1/+1
add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

2005-05-06[PATCH] DAC960: add support for Mylex AcceleRAID 4/5/600Christoph Hellwig1-0/+132
This patch adds support for a new class of DAC960 controllers. It's based on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a fork of the 2.4.18 version of DAC960 that adds support for this new type of controllers (internally called "GEM Series"), that differ from other DAC960 V2 firmware controllers only in the register offsets and removes support for all others. This patch instead integrates support for these controllers into the DAC960 driver. Thanks to Anders Norrbring for pointing me to the idac320 driver and testing this patch. No Signed-Off: line because all code is either copy & pasted from IBM's idac320 driver or support for other controllers in the 2.6 DAC960 driver. Note: the really odd formating matches the rest of the DAC960 driver. Cc: Dave Olien <dmo@osdl.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+7099
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
