++ help
++ This is support for devfs, a virtual file system (like /proc) which
++ provides the file system interface to device drivers, normally found
++ in /dev. Devfs does not depend on major and minor number
++ allocations. Device drivers register entries in /dev which then
++ appear automatically, which means that the system administrator does
++ not have to create character and block special device files in the
++ /dev directory using the mknod command (or MAKEDEV script) anymore.
++
++ This is work in progress. If you want to use this, you *must* read
++ the material in <file:Documentation/filesystems/devfs/>, especially
++ the file README there.
++
++ Note that devfs no longer manages /dev/pts! If you are using UNIX98
++ ptys, you will also need to mount the /dev/pts filesystem (devpts).
++
++ Note that devfs has been obsoleted by udev,
++ <http://www.kernel.org/pub/linux/utils/kernel/hotplug/>.
++ It has been stripped down to a bare minimum and is only provided for
++ legacy installations that use its naming scheme which is

++ select ZLIB_INFLATE
++ help
++ Saying Y here includes support for SquashFs 2.0 (Compressed Read-Only File
++ System). Squashfs is a highly compressed read-only filesystem for Linux.
++ It uses zlib compression to compress both files, inodes and directories.
++ Inodes in the system are very small and all blocks are packed to minimise
++ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
++
++ Squashfs is intended for general read-only filesystem use, for archival
++ use (i.e. in cases where a .tar.gz file may be used), and in embedded
++ systems where low overhead is needed. Further information and filesystem tools
++ are available from http://squashfs.sourceforge.net.
++
++ If you want to compile this as a module ( = code which can be
++ inserted in and removed from the running kernel whenever you want),
++ say M here and read <file:Documentation/modules.txt>. The module
++ will be called squashfs. Note that the root file system (the one
++ containing the directory /) cannot be compiled as a module.
++
++ If unsure, say N.
++

++ int "Number of fragments cached" if SQUASHFS_EMBEDDED
++ depends on SQUASHFS
++ default "3"
++ help
++ By default SquashFS caches the last 3 fragments read from
++ the filesystem. Increasing this amount may mean SquashFS
++ has to re-read fragments less often from disk, at the expense
++ of extra system memory. Decreasing this amount will mean
++ SquashFS uses less memory at the expense of extra reads from disk.
++
++ Note there must be at least one cached fragment. Anything
++ much more than three will probably not make much difference.
++
++config SQUASHFS_VMALLOC
++ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED
++ depends on SQUASHFS

++ help
++ By default SquashFS uses kmalloc to obtain fragment cache memory.
++ Kmalloc memory is the standard kernel allocator, but it can fail
++ on memory constrained systems. Because of the way Vmalloc works,
++ Vmalloc can succeed when kmalloc fails. Specifying this option
++ will make SquashFS always use Vmalloc to allocate the
++ fragment cache memory.

++ * have one of the subtle syntax dependencies: an individual BRANCH (as
++ * opposed to a collection of them) is never concatenated with anything
++ * because of operator precedence.) The operand of some types of node is
++ * a literal string; for others, it is a node leading into a sub-FSM. In
++ * particular, the operand of a BRANCH node is the first node of the branch.
++ * (NB this is *not* a tree structure: the tail of the branch connects

++ PF_RING socket family, optimized for packet capture.
++ If a PF_RING socket is bound to an adapter (via the bind() system
++ call), such adapter will be used in read-only mode until the socket
++ is destroyed. Whenever an incoming packet is received from the adapter
++ it will not passed to upper layers, but instead it is copied to a ring
++ buffer, which in turn is exported to user space applications via mmap.
++ Please refer to http://luca.ntop.org/Ring.pdf for more.
