Squashed file system support" ++ select ZLIB_INFLATE ++ help ++ Saying Y here includes support for SquashFS 3.2 (a 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 3.1 supports 64 bit filesystems and files (larger than 4GB), full ++ uid/gid information, hard links and timestamps. ++ ++ 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 . 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. ++ ++config SQUASHFS_EMBEDDED ++ ++ bool "Additional options for memory-constrained systems" ++ depends on SQUASHFS ++ default n ++ help ++ Saying Y here allows you to specify cache sizes and how Squashfs ++ allocates memory. This is only intended for memory constrained ++ systems. ++ ++ If unsure, say N. ++ ++config SQUASHFS_FRAGMENT_CACHE_SIZE ++ 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 ++ default n ++ 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. ++ ++ If unsure, say N. ++ + config VXFS_FS + tristate "FreeVxFS file system support (VERITAS VxFS(TM) compatible)" + depends on BLOCK +diff -x .gitignore -Nurp linux-2.6.20/fs/Makefile linux-2.6.20-squashfs3.2-r2/fs/Makefile +--- linux-2.6.20/fs/Makefile 2006-12-25 01:13:12.000000000 +0000 ++++ linux-2.6.20-squashfs3.2-r2/fs/Makefile 2007-01-16 02:06:03.000000000 +0000 +@@ -68,6 +68,7 @@ obj-$(CONFIG_JBD) += jbd/ + obj-$(CONFIG_JBD2) += jbd2/ + obj-$(CONFIG_EXT2_FS) += ext2/ + obj-$(CONFIG_CRAMFS) += cramfs/ ++obj-$(CONFIG_SQUASHFS) += squashfs/ + obj-$(CONFIG_RAMFS) += ramfs/ + obj-$(CONFIG_HUGETLBFS) += hugetlbfs/ + obj-$(CONFIG_CODA_FS) += coda/ +diff -x .gitignore -Nurp linux-2.6.20/fs/squashfs/inode.c linux-2.6.20-squashfs3.2-r2/fs/squashfs/inode.c +--- linux-2.6.20/fs/squashfs/inode.c 1970-01-01 01:00:00.000000000 +0100 ++++ linux-2.6.20-squashfs3.2-r2/fs/squashfs/inode.c 2007-01-16 02:28:36.000000000 +0000 +@@ -0,0 +1,2329 @@ ++/* ++ * Squashfs - a compressed read only filesystem for Linux ++ * ++ * Copyright (c) 2002, 2003, 2004, 2005, 2006, 2007 ++ * Phillip Lougher ++ * ++ * This program is free software; you can redistribute it and/or ++ * modify it under the terms of the GNU General Public License ++ * as published by the Free Software Foundation; either version 2, ++ * or (at your option) any later version. ++ * ++ * This program is distributed in the hope that it will be useful, ++ * but WITHOUT ANY WARRANTY; without even the implied warranty of ++ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
