Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ This is the journaling version of the Second extended file system

+ (method to organize files on a storage device) for hard disks.
+
+ The journaling code included in this driver means you do not have
+ to run e2fsck (file system checker) on your file systems after a
+ crash. The journal keeps track of any changes that were being made
+ at the time the system crashed, and can ensure that your file system
+ is consistent without the need for a lengthy check.
+
+ Other than adding the journal to the file system, the on-disk format
+ of ext3 is identical to ext2. It is possible to freely switch
+ between using the ext3 driver and the ext2 driver, as long as the
+ file system has been cleanly unmounted, or e2fsck is run on the file
+ system.
+
+ To add a journal on an existing ext2 file system or change the
+ behavior of ext3 file systems, you can use the tune2fs utility ("man
+ tune2fs"). To modify attributes of files and directories on ext3
+ file systems, use chattr ("man chattr"). You need to be using

+ help
+ This is the client VFS module for the Common Internet File System

+ (SMB) protocol, the native file sharing mechanism for most early
+ PC operating systems. The CIFS protocol is fully supported by
+ file servers such as Windows 2000 (including Windows 2003, NT 4
+ and Windows XP) as well by Samba (which provides excellent CIFS
+ server support for Linux and many other operating systems). Currently
+ you must use the smbfs client filesystem to access older SMB servers
+ such as Windows 9x and OS/2.
+
+ The intent of the cifs module is to provide an advanced
+ network file system client for mounting to CIFS compliant servers,
+ including support for dfs (hierarchical name space), secure per-user
+ session establishment, safe distributed caching (oplock), optional
+ packet signing, Unicode and other internationalization improvements,
+ and optional Winbind (nsswitch) integration. You do not need to enable
+ cifs if running only a (Samba) server. It is possible to enable both
+ smbfs and cifs (e.g. if you are using CIFS for accessing Windows 2003
