Drivers: block: remove __dev* attributes.

2013-01-03T23:57:15Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Merge branch 'for-3.8/drivers' of git://git.kernel.dk/linux-block

2012-12-17T21:39:11Z

Pull block driver update from Jens Axboe: "Now that the core bits are in, here are the driver bits for 3.8. The branch contains: - A huge pile of drbd bits that were dumped from the 3.7 merge window. Following that, it was both made perfectly clear that there is going to be no more over-the-wall pulls and how the situation on individual pulls can be improved. - A few cleanups from Akinobu Mita for drbd and cciss. - Queue improvement for loop from Lukas. This grew into adding a generic interface for waiting/checking an even with a specific lock, allowing this to be pulled out of md and now loop and drbd is also using it. - A few fixes for xen back/front block driver from Roger Pau Monne. - Partition improvements from Stephen Warren, allowing partiion UUID to be used as an identifier." * 'for-3.8/drivers' of git://git.kernel.dk/linux-block: (609 commits) drbd: update Kconfig to match current dependencies drbd: Fix drbdsetup wait-connect, wait-sync etc... commands drbd: close race between drbd_set_role and drbd_connect drbd: respect no-md-barriers setting also when changed online via disk-options drbd: Remove obsolete check drbd: fixup after wait_even_lock_irq() addition to generic code loop: Limit the number of requests in the bio list wait: add wait_event_lock_irq() interface xen-blkfront: free allocated page xen-blkback: move free persistent grants code block: partition: msdos: provide UUIDs for partitions init: reduce PARTUUID min length to 1 from 36 block: store partition_meta_info.uuid as a string cciss: use check_signature() cciss: cleanup bitops usage drbd: use copy_highpage drbd: if the replication link breaks during handshake, keep retrying drbd: check return of kmalloc in receive_uuids drbd: Broadcast sync progress no more often than once per second drbd: don't try to clear bits once the disk has failed ...

cciss: use check_signature()

2012-11-23T13:28:34Z

Use check_signature() to find a signature in the mmio address. Signed-off-by: Akinobu Mita Cc: Mike Miller Cc: Stephen M. Cameron Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

cciss: cleanup bitops usage

2012-11-23T13:27:22Z

- Remove unnecessary correction of bit and address - Use BITS_TO_LONGS macro to calculate bitmap size - Use bitmap_zero() Signed-off-by: Akinobu Mita Cc: Mike Miller Cc: Stephen M. Cameron Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

cciss: remove unneeded memset()

2012-10-30T07:36:58Z

The memory return by kzalloc() or kmem_cache_zalloc() has already be set to zero, so remove useless memset(0). spatch with a semantic match is used to found this problem.

block: add and use scsi_blk_cmd_ioctl

2012-01-14T23:07:24Z

Introduce a wrapper around scsi_cmd_ioctl that takes a block device. The function will then be enhanced to detect partition block devices and, in that case, subject the ioctls to whitelisting.

cciss: fix flush cache transfer length

2011-11-28T19:12:05Z

We weren't filling in the transfer length of the flush cache command (it transfers 4 bytes of zeroes). Firmware didn't seem to be bothered by this, but it should be fixed. Signed-off-by: Stephen M. Cameron Signed-off-by: Jens Axboe

cciss: Add IRQF_SHARED back in for the non-MSI(X) interrupt handler

2011-11-28T19:12:05Z

IRQF_SHARED is required for older controllers that don't support MSI(X) and which may end up sharing an interrupt. Also remove deprecated IRQF_DISABLED. Signed-off-by: Stephen M. Cameron Signed-off-by: Jens Axboe

cciss: auto engage SCSI mid layer at driver load time

2011-11-16T08:21:49Z

A long time ago, probably in 2002, one of the distros, or maybe more than one, loaded block drivers prior to loading the SCSI mid layer. This meant that the cciss driver, being a block driver, could not engage the SCSI mid layer at init time without panicking, and relied on being poked by a userland program after the system was up (and the SCSI mid layer was therefore present) to engage the SCSI mid layer. This is no longer the case, and cciss can safely rely on the SCSI mid layer being present at init time and engage the SCSI mid layer straight away. This means that users will see their tape drives and medium changers at driver load time without need for a script in /etc/rc.d that does this: for x in /proc/driver/cciss/cciss* do echo "engage scsi" > $x done However, if no tape drives or medium changers are detected, the SCSI mid layer will not be engaged. If a tape drive or medium change is later hot-added to the system it will then be necessary to use the above script or similar for the device(s) to be acceesible. Signed-off-by: Stephen M.

The Windows driver .inf disables ASPM on all cciss devices. Do the same.
