Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
"A set of fixes for the current series, one fixing a regression with
block size < page cache size in the alias series from Jan. Outside of
that, two small cleanups for wbt from Bart, a nvme pull request from
Christoph, and a few small fixes of documentation updates"
* 'for-linus' of git://git.kernel.dk/linux-block:
block: fix up io_poll documentation
block: Avoid that sparse complains about context imbalance in __wbt_wait()
block: Make wbt_wait() definition consistent with declaration
clean_bdev_aliases: Prevent cleaning blocks that are not in block range
genhd: remove dead and duplicated scsi code
block: add back plugging in __blkdev_direct_IO
nvmet/fcloop: remove some logically dead code performing redundant ret checks
nvmet: fix KATO offset in Set Features
nvme/fc: simplify error handling of nvme_fc_create_hw_io_queues
nvme/fc: correct some printk information
nvme/scsi: Remove START STOP emulation
nvme/pci: Delete misleading queue-wrap comment
nvme/pci: Fix whitespace problem
nvme: simplify stripe quirk
nvme: update maintainers information

This file documents the NCR53c400 extensions by Kevin Lentin and some
enhancements to the NCR5380 core.
-This driver supports both NCR5380 and NCR53c400 cards in port or memory
-mapped modes. Currently this driver can only support one of those mapping
-modes at a time but it does support both of these chips at the same time.
-The next release of this driver will support port & memory mapped cards at
-the same time. It should be able to handle multiple different cards in the
-same machine.
+This driver supports NCR5380 and NCR53c400 and compatible cards in port or
+memory mapped modes.
-The drivers/scsi/Makefile has an override in it for the most common
-NCR53c400 card, the Trantor T130B in its default configuration:
- Port: 0x350
- IRQ : 5
+Use of an interrupt is recommended, if supported by the board, as this will
+allow targets to disconnect and thereby improve SCSI bus utilization.
+
+If the irq parameter is 254 or is omitted entirely, the driver will probe
+for the correct IRQ line automatically. If the irq parameter is 0 or 255
+then no IRQ will be used.
The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
supported by the driver.

- This option provides a kernel module that can be used to test
- the error handling of the cpu notifiers by injecting artificial
- errors to CPU notifier chain callbacks. It is controlled through
- debugfs interface under /sys/kernel/debug/notifier-error-inject/cpu
-
- If the notifier call chain should be failed with some events
- notified, write the error code to "actions/<notifier event>/error".
-
- Example: Inject CPU offline error (-1 == -EPERM)
-
- # cd /sys/kernel/debug/notifier-error-inject/cpu
- # echo -1 > actions/CPU_DOWN_PREPARE/error
- # echo 0 > /sys/devices/system/cpu/cpu1/online
- bash: echo: write error: Operation not permitted
-
- To compile this code as a module, choose M here: the module will
- be called cpu-notifier-error-inject.
-
- If unsure, say N.
