2007-10-24SG: audit of drivers that use blk_rq_map_sg()Jens Axboe
They need to properly init the sg table, or blk_rq_map_sg() will complain if CONFIG_DEBUG_SG is set. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-11[POWERPC] iSeries: Move detection of virtual cdromsStephen Rothwell
Now we will only have entries in the device tree for the actual existing devices (including their OS/400 properties). This way viocd.c gets all the information about the devices from the device tree.

2007-10-11[POWERPC] Remove iSeries_vio_devStephen Rothwell
It was only being used to carry around dma_iommu_ops and vio_iommu_table which we can use directly instead. This also means that vio_bus_device doesn't need to refer to them either.

2007-10-11[POWERPC] iSeries: Simplify viocd initialisationStephen Rothwell
We don't need to keep a lump of dma coherent memory around for the life of the module. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-24[BLOCK] Get rid of request_queue_t typedefJens Axboe
Some of the code has been gradually transitioned to using the proper struct request_queue, but there's lots left. So do a full sweet of the kernel and get rid of this typedef and replace its uses with the proper type. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-03-05[PATCH] Fix soft lockup with iSeries viocd driverTony Breeds
Fix soft lockup with iSeries viocd driver, caused by eventually calling end_that_request_first() with nr_bytes 0. Some versions of hald do an SG_IO ioctl on the viocd device which becomes a request with hard_nr_sectors and hard_cur_sectors set to zero. Passing zero as the number of sectors to end_request() (which calls end_that_request_first()) causes an infinite loop when the bio is being freed. This patch makes sure that the zero is never passed. It only requires some number larger the the request size the terminate the loop. The lockup is triggered by hald, interrogating the device.

2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-06-26[PATCH] devfs: Last little devfs cleanups throughout the kernel tree.Greg Kroah-Hartman
Just removes a few unused #defines and fixes some comments due to devfs now being gone. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-06-26[PATCH] devfs: Remove the gendisk devfs_name field as it's no longer neededGreg Kroah-Hartman
And remove the now unneeded number field. Also fixes all drivers that set these fields. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-05-19[PATCH] powerpc: update iSeries viocd and viotape device-treeStephen Rothwell
Make their device_type entries more generic and their compatible entries more specific. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-03-23[PATCH] kill cdrom ->dev_ioctl methodChristoph Hellwig
Since early 2.4.x all cdrom drivers implement the block_device methods themselves, so they can handle additional ioctls directly instead of going through the cdrom layer.

2005-05-28[PATCH] ppc64 iSeries: make virtual DVD-RAMs writable againStephen Rothwell
It appears that another test has been added in the Uniform CDROM layer that must be passed before a DVD-RAM is considered writeable.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
