This driver supports certain USB attached storage devices
such as flash keys.
- Warning: Enabling this cripples the usb-storage driver.
-
If unsure, say N.
config BLK_DEV_RAM
Most normal users won't need the RAM disk functionality, and can
thus say N here.
-config BLK_DEV_RAM_COUNT
- int "Default number of RAM disks" if BLK_DEV_RAM
- default "16"
- help
- The default value is 16 RAM disks. Change this if you know what
- are doing. If you boot from a filesystem that needs to be extracted
- in memory, you will need at least one RAM disk (e.g. root on cramfs).
-
config BLK_DEV_RAM_SIZE
int "Default RAM disk size (kbytes)"
depends on BLK_DEV_RAM
"real" root file system, etc. See <file:Documentation/initrd.txt>
for details.
-config INITRAMFS_SOURCE
- string "Source directory of cpio_list"
- default ""
- help
- This can be set to either a directory containing files, etc to be
- included in the initramfs archive, or a file containing newline
- separated entries.
-
- If it is a file, it should be in the following format:
- # a comment
- file <name> <location> <mode> <uid> <gid>
- dir <name> <mode> <uid> <gid>
- nod <name> <mode> <uid> <gid> <dev_type> <maj> <min>
-
- Where:
- <name> name of the file/dir/nod in the archive
- <location> location of the file in the current filesystem
- <mode> mode/permissions of the file
- <uid> user id (0=root)
- <gid> group id (0=root)
- <dev_type> device type (b=block, c=character)
- <maj> major number of nod
- <min> minor number of nod
-
- If you are not sure, leave it blank.

config LBD
bool "Support for Large Block Devices"
depends on X86 || MIPS32 || PPC32 || ARCH_S390_31 || SUPERH
your machine, or if you want to have a raid or loopback device
bigger than 2TB. Otherwise say N.
-config CDROM_PKTCDVD
- tristate "Packet writing on CD/DVD media"
- help
- If you have a CDROM drive that supports packet writing, say Y to
- include preliminary support. It should work with any MMC/Mt Fuji
- compliant ATAPI or SCSI drive, which is just about any newer CD
- writer.
-
- Currently only writing to CD-RW, DVD-RW and DVD+RW discs is possible.
- DVD-RW disks must be in restricted overwrite mode.
-
- To compile this driver as a module, choose M here: the
- module will be called pktcdvd.
-
-config CDROM_PKTCDVD_BUFFERS
- int "Free buffers for data gathering"
- depends on CDROM_PKTCDVD
- default "8"
- help
- This controls the maximum number of active concurrent packets. More
- concurrent packets can increase write performance, but also require
- more memory. Each concurrent packet will require approximately 64Kb
- of non-swappable kernel memory, memory which will be allocated at
- pktsetup time.
-
-config CDROM_PKTCDVD_WCACHE
- bool "Enable write caching"
- depends on CDROM_PKTCDVD
- help
- If enabled, write caching will be set for the CD-R/W device. For now
- this option is dangerous unless the CD-RW media is known good, as we
- don't do deferred write error handling yet.
-
-config DISKDUMP
- tristate "Disk dump support"
