Undetected edge case for CRT messages to CEX2A caused length to be too short, thus truncating the message. The solution was to check a different variable which actually determines which key type is being used. Increment version number in z90main.c to correct level of 1.3.3, fix copyright year and add comment about bitlength limit of CEX2A. Signed-off-by:

If a tape device is assigned to another host, the interrupt for the assign operation comes back with deferred condition code 1. Under some conditions this can lead to an endless loop of retries. Check if the current request is still in IO in deferred condition code handling and prevent retries when the request has already been cancelled. Signed-off-by:

When a request is aborted because of a signal, we currently stop the request via csh, but we do not wait for the interrupt of csh in any case. We free the request structure and therefore when the interrupt for the csh operation is presented, the request object is no longer valid and an invalid callback pointer is used. To fix this wait until the interrupt for csh arrives and until wait_event_interruptible() does not return -ERESTARTSYS. Signed-off-by:

Stefan Bader authored
If a deferred CC happens there will be lots of messages, because the retry is done immediatly in the interrupt handler which can be too fast. To avoid this requeue the request and schedule the queue to be processed. Signed-off-by:

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. Signed-off-by:

dasd_cmd just implements three ioctls which are wrappers around functionality in the core kernel or other modules. When merging those into dasd_mod they just add 22 lines of code which is far less than the amount of code removed in the last two patches, and which doesn't spill into another 4k pages when build modular, while removing a 128lines module.

Add an ->ioctl method to the dasd_discipline structure. This allows to apply the same kind of cleanups the last patch applied to dasd_ioctl.c to dasd_eckd.c (the only dasd discipline with special ioctls) aswell. Again lots of code removed. During auditing the ioctls I found two fishy return value propagations from copy_{from,to}_user, maintainers please check those, I've marked them with XXX comments. Signed-off-by: -
Christoph Hellwig authored
Handle ioctls implemented in dasd_ioctl through the normal switch statement that most drivers use instead of the awkward dasd_ioctl_no_register routine. This avoids searching a linear list on every call to dasd_ioctl(), and allows to give the various ioctl implementation functions sane prototypes, aswell as moving the check for bdev->bd_disk->private_data from the individual functions to dasd_ioctl. (I think it can't actually every be NULL, but let's keep that for later) Signed-off-by:

When cio waits for the interrupt for a basic sense, interrupts for hsch() or csch() issued in the meantime are wrongly counted as interrupts for the basic sense and the accumulated irb is passed to the device driver. In ccw_device_w4sense(), check for clear or halt function in the irb and pass the irb for the csch() or hsch() to the device driver. Signed-off-by:

While working on these patch set, I found several possible cleanup on x86-64 and ia64. akpm: I stole this from Andi's queue. Not only does it clean up bitops. It also unrelatedly changes the prototype of pci_mmcfg_init() and removes its arch_initcall(). It seems that the wrong two patches got joined together, but this is the one which has been tested. This patch fixes the current x86_64 build error (the pci_mmcfg_init() declaration in arch/i386/pci/pci.h disagrees with the definition in arch/x86_64/pci/mmconfig.c) This also means that x86_64's pci_mmcfg_init() gets called in the same (new) manner as x86's: from arch/i386/pci/init.c:pci_access_init(), rather than via initcall. The bitops cleanups came along for free. All this worked OK in -mm testing (since 2.6.16-rc4-mm1) because x86_64 was tested with both patches applied. Signed-off-by:

The meaning of MS_VERBOSE is backwards; if the bit is set, it really means, "don't be verbose". This is confusing and counter-intuitive. In addition, there is also no way to set the MS_VERBOSE flag in the mount(8) program in util-linux, but interesting, it does define options which would do the right thing if MS_SILENT were defined, which unfortunately we do not: #ifdef MS_SILENT { "quiet", 0, 0, MS_SILENT }, /* be quiet */ { "loud", 0, 1, MS_SILENT }, /* print out messages. */ #endif So the obvious fix is to deprecate the use of MS_VERBOSE and replace it with MS_SILENT.
