+       select FS_IOMAP

+       help
+	 Provide block layer support for the kernel.
+
+	 Disable this option to remove the block layer support from the
+	 kernel. This may be useful for embedded devices.
+
+	 If this option is disabled:
+
+	   - block device files will become unusable
+	   - some filesystems (such as ext3) will become unavailable.
+
+	 Also, SCSI character devices and USB storage will be disabled since
+	 they make use of various block layer definitions and facilities.
+
+	 Say Y here unless you know you really don't want to mount disks and
+	 suchlike.

+if BLOCK
+
+config BLOCK_LEGACY_AUTOLOAD
+	bool "Legacy autoloading support"
+	default y
+	help
+	  Enable loading modules and creating block device instances based on
+	  accesses through their device special file.  This is a historic Linux
+	  feature and makes no sense in a udev world where device files are
+	  created on demand, but scripts that manually create device nodes and
+	  then call losetup might rely on this behavior.

+config BLK_DEV_INTEGRITY
+	bool "Block layer data integrity support"
+	select CRC_T10DIF
+	select CRC64
+	help
+	Some storage devices allow extra information to be
+	stored/retrieved to help protect the data.  The block layer
+	data integrity option provides hooks which can be used by
+	filesystems to ensure better data integrity.
+
+	Say yes here if you have a storage device that provides the
+	T10/SCSI Data Integrity Field or the T13/ATA External Path
+	Protection.  If in doubt, say N.
+
+config BLK_DEV_WRITE_MOUNTED
+	bool "Allow writing to mounted block devices"
+	default y
+	help
+	When a block device is mounted, writing to its buffer cache is very
+	likely going to cause filesystem corruption. It is also rather easy to
+	crash the kernel in this way since the filesystem has no practical way
+	of detecting these writes to buffer cache and verifying its metadata
+	integrity. However there are some setups that need this capability
+	like running fsck on read-only mounted root device, modifying some
+	features on mounted ext4 filesystem, and similar. If you say N, the
+	kernel will prevent processes from writing to block devices that are
+	mounted by filesystems which provides some more protection from runaway
+	privileged processes and generally makes it much harder to crash
+	filesystem drivers. Note however that this does not prevent
+	underlying device(s) from being modified by other means, e.g. by
+	directly submitting SCSI commands or through access to lower layers of
+	storage stack. If in doubt, say Y. The configuration can be overridden
+	with the bdev_allow_write_mounted boot option.
+
+config BLK_DEV_ZONED
+	bool "Zoned block device support"
+	help
+	Block layer zoned block device support. This option enables
+	support for ZAC/ZBC/ZNS host-managed and host-aware zoned block
+	devices.
+
+	Say yes here if you have a ZAC, ZBC, or ZNS storage device.
+
+config BLK_DEV_THROTTLING
+	bool "Block layer bio throttling support"
+	depends on BLK_CGROUP
+	select BLK_CGROUP_RWSTAT
+	help
+	Block layer bio throttling support. It can be used to limit
+	the IO rate to a device. IO rate policies are per cgroup and
+	one needs to mount and use blkio cgroup controller for creating
+	cgroups and specifying per device IO rate policies.
+
+	See Documentation/admin-guide/cgroup-v1/blkio-controller.rst for more information.
+
+config BLK_WBT
+	bool "Enable support for block device writeback throttling"
+	help
+	Enabling this option enables the block layer to throttle buffered
+	background writeback from the VM, making it more smooth and having
+	less impact on foreground operations. The throttling is done
+	dynamically on an algorithm loosely based on CoDel, factoring in
+	the realtime performance of the disk.
+
+config BLK_WBT_MQ
+	bool "Enable writeback throttling by default"
+	default y
+	depends on BLK_WBT
+	help
+	Enable writeback throttling by default for request-based block devices.
+
+config BLK_CGROUP_IOLATENCY
+	bool "Enable support for latency based cgroup IO protection"
+	depends on BLK_CGROUP
+	help
+	Enabling this option enables the .latency interface for IO throttling.
+	The IO controller will attempt to maintain average IO latencies below
+	the configured latency target, throttling anybody with a higher latency
+	target than the victimized group.
+
+	Note, this is an experimental interface and could be changed someday.
+
+config BLK_CGROUP_FC_APPID
+	bool "Enable support to track FC I/O Traffic across cgroup applications"
+	depends on BLK_CGROUP && NVME_FC
+	help
+	  Enabling this option enables the support to track FC I/O traffic across
+	  cgroup applications. It enables the Fabric and the storage targets to
+	  identify, monitor, and handle FC traffic based on VM tags by inserting
+	  application specific identification into the FC frame.
+
+config BLK_CGROUP_IOCOST
+	bool "Enable support for cost model based cgroup IO controller"
+	depends on BLK_CGROUP
+	select BLK_RQ_ALLOC_TIME
+	help
+	Enabling this option enables the .weight interface for cost
+	model based proportional IO control.  The IO controller
+	distributes IO capacity between different groups based on
+	their share of the overall weight distribution.
+
+config BLK_CGROUP_IOPRIO
+	bool "Cgroup I/O controller for assigning an I/O priority class"
+	depends on BLK_CGROUP
+	help
+	Enable the .prio interface for assigning an I/O priority class to
+	requests. The I/O priority class affects the order in which an I/O
+	scheduler and block devices process requests. Only some I/O schedulers
+	and some block devices support I/O priorities.
+
+config BLK_DEBUG_FS
+	bool "Block layer debugging information in debugfs"
+	default y
+	depends on DEBUG_FS
+	help
+	Include block layer debugging information in debugfs. This information
+	is mostly useful for kernel developers, but it doesn't incur any cost
+	at runtime.
+
+	Unless you are building a kernel for a tiny system, you should
+	say Y here.
+
+config BLK_SED_OPAL
+	bool "Logic for interfacing with Opal enabled SEDs"
+	depends on KEYS
+	select PSERIES_PLPKS if PPC_PSERIES
+	select PSERIES_PLPKS_SED if PPC_PSERIES
+	help
+	Builds Logic for interfacing with Opal enabled controllers.
+	Enabling this option enables users to setup/unlock/lock
+	Locking ranges for SED devices using the Opal protocol.
+
+config BLK_INLINE_ENCRYPTION
+	bool "Enable inline encryption support in block layer"
+	help
+	  Build the blk-crypto subsystem. Enabling this lets the
+	  block layer handle encryption, so users can take
+	  advantage of inline encryption hardware if present.
+
+config BLK_INLINE_ENCRYPTION_FALLBACK
+	bool "Enable crypto API fallback for blk-crypto"
+	depends on BLK_INLINE_ENCRYPTION
+	select CRYPTO
+	select CRYPTO_SKCIPHER
+	help
+	  Enabling this lets the block layer handle inline encryption
+	  by falling back to the kernel crypto API when inline
+	  encryption hardware is not present.
