Add LBPRZ support to scsi_debug; i.e. read zeros for unmapped blocks. Rather than checking for unmapped blocks at read time, this just zeroes them on the backing store at unmap time so it behaves the same way. This also adds a module parameter to disable it. lbprz, "unmapped blocks return 0 on read (def=1)" [jejb: fix whitespace errors] Signed-off-by:

If a ping or host event were to occur when memory is low we do not want to use GFP_KERNEL, because the paths sending them cannot block for data to be written. These paths might be needed to recover write paths. Use GFP_NOIO instead. Signed-off-by:

Casting pointer from native data type to other type is endian-sensitive. "iocmd->offset" is 64 bit but we use only first 32 bit. It works in little-endian system but in big-endian system it will break. Signed-off-by:

The st tape driver recently added the MTWEOFI ioctl, which writes a tape filemark (EOF), like the MTWEOF ioctl, except that MTWEOFI returns immediately. This makes certain applications, like backup software, run much more quickly on buffered tape drives. Since legacy applications do not know about this new MTWEOFI ioctl, this patch adds a new ioctl option that tells the st driver to return immediately when writing an EOF (i.e. a filemark). This new flag is much like the existing flag that tells the st driver to perform writes (and certain other IOs) immediately, but this new flag only applies to writing EOFs. This new feature is controlled via the MTSETDRVBUFFER ioctl, using the newly-defined MT_ST_NOWAIT_EOF flag. Use of this new feature is displayed via the sysfs tape "options" attribute. The st documentation was updated to mention this new flag, as well as the problems that can occur from using it. Signed-off-by:

This patch adds support for Universal Flash Storage(UFS) host controllers. The UFS host controller driver includes host controller initialization method. The Initialization process involves following steps: - Initiate UFS Host Controller initialization process by writing to Host controller enable register - Configure UFS Host controller registers with host memory space datastructure offsets. - Unipro link startup procedure - Check for connected device - Configure UFS host controller to process requests - Enable required interrupts - Configure interrupt aggregation [jejb: fix warnings in 32 bit compile] Signed-off-by:

The sd_check_event() will be called periodly even when the device is in the suspended status to check media event. The scsi_test_unit_ready() in the sd_check_event() will issue scsi cmd request. Issuing scsi request when the device is in the suspeneded status will cause problem. For example, when a usb flash disk in the suspended status, scsi_test_unit_ready() issues a scsi request. The request will be returned as failed because the usb device is not active. The patch adds scsi_autopm_get_device() and scsi_autopm_put_device() around scsi_test_unit_ready() in the sd_check_event() to resolve such problem. Signed-off-by:
