-Release February 15, 2002 (version 1.0.15)
-This is our fifty-third release of IBM's Enterprise JFS technology port to Linux.
-Beta 1 was release 0.1.0 on 12/8/2000, Beta 2 was release 0.2.0 on 3/7/2001, 
-Beta 3 was release 0.3.0 on 4/30/2001, and release 1.0.0 on 6/28/2001.
-The changelog.jfs file contains detailed information of changes done in each source
-code drop.
-JFS has a source tree that can be built on 2.4.3 - 2.4.17 and 2.5.4 kernel.org
-source trees.
-Our current goal on the 2.5.x series of the kernel is to update to the latest 
-2.5.x version and only support the latest version of this kernel.
-This will change when the distros start shipping the 2.5.x series of the kernel.
-Our current goal on the 2.4.x series of the kernel is to continue to support
-all of the kernels in this series as we do today.
-There is an anonymous cvs access available for the JFS tree. The steps below are
-what is needed to pull the JFS cvs tree from the oss.software.ibm.com server.
-id anoncvs
-password anoncvs
-To checkout 2.4.x series of the JFS files do the following:
-CVSROOT should be set to :pserver:anoncvs@oss.software.ibm.com:/usr/cvs/jfs
-cvs checkout linux24
-To checkout 2.5.2 series of the JFS files do the following:
-CVSROOT should be set to :pserver:anoncvs@oss.software.ibm.com:/usr/cvs/jfs
-cvs checkout linux25
-To checkout the JFS utilities do the following:
-CVSROOT should be set to :pserver:anoncvs@oss.software.ibm.com:/usr/cvs/jfs
-cvs checkout jfsutils
-The cvs tree contains the latest changes being done to JFS. To receive notification
-of commits to the cvs tree, please send e-mail to linuxjfs@us.ibm.com stating that 
-you would like notifications sent to you. 
-The jfs-2.4-1.0.15-patch.tar.gz is the easiest way to get the latest file system
-source code on your system. There are also patch files that can move your jfs source
-code from one release to another. If you have release 1.0.14 and would like to move
-to release 1.0.15 the patch file named jfs-2.4-1_0_14-to-1_0_15-patch.gz will do that.
-The jfs-2.4-1.0.15-patch.tar.gz file contains a readme and patch files for different
-levels of the 2.4 kernel. Please see the README in the jfs-2.4-1.0.15-patch.tar.gz
-file for help on applying the two patch files. 
-The following files in the kernel source tree have been changed so JFS can be built.
-The jfs-2.4-1.0.15.tar.gz source tar ball contains each of the files below with
-the extension of the kernel level it is associated with. As an example, there are now
-four Config.in files named Config.in-2.4.0, Config.in-2.4.5, Config.in-2.4.7 and 
-Config.in-2.4.17.
-If you use the jfs-2.4-1.0.15.tar.gz to build JFS you must rename each of the 
-kernel files to the file names listed below. The standard kernel from www.kernel.org 
-is the source of the kernel files that are included in the jfs tar file. 
-In sub dir fs Config.in, Makefile
-In sub dir fs/nls Config.in
-In sub dir Documentation Configure.help, Changes
-In sub dir Documentation/filesystems 00-INDEX
-In sub dir linux MAINTAINERS
-Please backup the above files before the JFS tar file is added to the kernel source 
+The following mount options are supported:
-tree. All JFS files are located in the include/linux/jfs or fs/jfs sub dirs.
-Our development team has used the Linux kernel levels  2.4.3 - 2.4.17 kernels
+iocharset=name	Character set to use for converting from Unicode to
-with gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) 
+		ASCII.  The default is compiled into the kernel as
-for our port so far. A goal of the JFS team is to have JFS run on all architectures
+		CONFIG_NLS_DEFAULT.  Use iocharset=utf8 for UTF8
-that Linux supports, there is no architecture specific code in JFS. JFS has been run
+		translations.  This requires CONFIG_NLS_UTF8 to be set
-on the following architectures (x86, PowerPC, Alpha, s/390, ARM) so far. 
+		in the kernel .config file.
-To make JFS build, during the "make config" step of building the kernel answer y to
-the Prompt for development and/or incomplete code/drivers in the Code maturity level
-options section. In the Filesystems section use the m for the answer to 
-JFS filesystem support (experimental) (CONFIG_JFS_FS) [Y/m/n?]
-Build in /usr/src/linux with the command:
-make modules
-make modules_install
-If you rebuild jfs.o after having mounted and unmounted a partition, "modprobe -r jfs" 
-will unload the old module.
-For the file system debugging messages are being written to /var/log/messages.
-Please see the readme in the utilities package for information about building
-the JFS utilities.
 JFS TODO list:
 Plans for our near term development items
-   - get defrag capabilities operational in the FS
+   - implement online resize for extending JFS volumes
-   - get extendfs capabilities operational in the FS
+   - enhance support for logfile on dedicated partition
-   - test EXTENDFS utility, for growing JFS partitions
+   - get access control list functionality operational
-   - test defrag utility, calls file system to defrag the file system.
+   - get extended attributes functionality operational
-   - add support for block sizes (512,1024,2048)
-   - add support for logfile on dedicated partition
 Longer term work items
-   - get access control list functionality operational
+   - implement defrag utility, for online defragmenting
-   - get extended attributes functionality operational
   - add quota support
+   - add support for block sizes (512,1024,2048)
