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!

121 | ---help--- | ||
122 | There are many external CD-ROM and disk devices that connect through | ||

125 | subsystem which contains drivers for many of these external drives. | ||
126 | Read <file:Documentation/paride.txt> for more information. | ||
127 | |||
128 | If you have said Y to the "Parallel-port support" configuration | ||
129 | option, you may share a single port between your printer and other | ||
130 | parallel port devices. Answer Y to build PARIDE support into your | ||
131 | kernel, or M if you would like to build it as a loadable module. If | ||
132 | your parallel port support is in a loadable module, you must build | ||
133 | PARIDE as a module. If you built PARIDE support into your kernel, | ||
134 | you may still build the individual protocol modules and high-level | ||
135 | drivers as loadable modules. If you build this support as a module, | ||

214 | ---help--- | ||
215 | The User-Mode Linux port includes a driver called UBD which will let | ||

221 | bool "Always do synchronous disk IO for UBD" | ||
222 | depends on BLK_DEV_UBD | ||
223 | ---help--- | ||
224 | Writes to the virtual block device are not immediately written to the | ||
225 | host's disk; this may cause problems if, for example, the User-Mode | ||
226 | Linux 'Virtual Machine' uses a journalling filesystem and the host | ||
227 | computer crashes. | ||
228 | |||
229 | Synchronous operation (i.e. always writing data to the host's disk | ||
230 | immediately) is configurable on a per-UBD basis by using a special | ||
231 | kernel command line option. Alternatively, you can say Y here to | ||
232 | turn on synchronous operation by default for all block devices. | ||
233 | |||
234 | If you're running a journalling file system (like reiserfs, for | ||
235 | example) in your virtual machine, you will want to say Y here. If | ||
236 | you care for the safety of the data in your virtual machine, Y is a | ||
237 | wise choice too. In all other cases (for example, if you're just | ||
238 | playing around with User-Mode Linux) you can choose N. | ||

247 | ---help--- | ||
248 | The User-Mode Linux port can provide support for IO Memory | ||
249 | emulation with this option. This allows a host file to be | ||
250 | specified as an I/O region on the kernel command line. That file | ||
251 | will be mapped into UML's kernel address space where a driver can | ||
252 | locate it and do whatever it wants with the memory, including | ||
253 | providing an interface to it for UML processes to use. | ||
254 | |||
255 | For more information, see | ||
256 | <http://user-mode-linux.sourceforge.net/iomem.html>. | ||

260 | |||
261 | config BLK_DEV_LOOP | ||
262 | tristate "Loopback device support" | ||
263 | ---help--- | ||
264 | Saying Y here will allow you to use a regular file as a block | ||
265 | device; you can then create a file system on that block device and | ||
266 | mount it just as you would mount other block devices such as hard | ||
267 | drive partitions, CD-ROM drives or floppy drives. The loop devices | ||
268 | are block special device files with major number 7 and typically | ||
269 | called /dev/loop0, /dev/loop1 etc. | ||
270 | |||
271 | This is useful if you want to check an ISO 9660 file system before | ||
272 | burning the CD, or if you want to use floppy images without first | ||
273 | writing them to floppy. Furthermore, some Linux distributions avoid | ||
274 | the need for a dedicated Linux partition by keeping their complete | ||
275 | root file system inside a DOS FAT file using this loop device | ||
276 | driver. | ||
277 | |||
278 | To use the loop device, you need the losetup utility, found in the | ||
279 | util-linux package, see | ||
280 | <ftp://ftp.kernel.org/pub/linux/utils/util-linux/>. | ||
281 | |||
282 | The loop device driver can also be used to "hide" a file system in | ||
283 | a disk partition, floppy, or regular file, either using encryption | ||
284 | (scrambling the data) or steganography (hiding the data in the low | ||
285 | bits of, say, a sound file). This is also safe if the file resides | ||
286 | on a remote file server. | ||
287 | |||
288 | There are several ways of encrypting disks. Some of these require | ||
289 | kernel patches. The vanilla kernel offers the cryptoloop option | ||
290 | and a Device Mapper target (which is superior, as it supports all | ||
291 | file systems). If you want to use the cryptoloop, say Y to both | ||
292 | LOOP and CRYPTOLOOP, and make sure you have a recent (version 2.12 | ||
293 | or later) version of util-linux. Additionally, be aware that | ||
294 | the cryptoloop is not safe for storing journaled filesystems. | ||
295 | |||
296 | Note that this loop device has nothing to do with the loopback | ||
297 | device used for network connections from the machine to itself. | ||
298 | |||
299 | To compile this driver as a module, choose M here: the | ||
300 | module will be called loop. | ||

313 | WARNING: This device is not safe for journaled file systems like | ||
314 | ext3 or Reiserfs. Please use the Device Mapper crypto module | ||
315 | instead, which can be configured to be on-disk compatible with the | ||

323 | block devices, i.e. it will be able to use block devices exported by | ||
324 | servers (mount file systems on them etc.). Communication between | ||
325 | client and server works over TCP/IP networking, but to the client | ||
326 | program this is hidden: it looks like a regular local file access to | ||
327 | a block device special file such as /dev/nd0. | ||
328 | |||
329 | Network block devices also allows you to run a block-device in | ||
330 | userland (making server and client physically the same computer, | ||
331 | communicating using the loopback network device). | ||
332 | |||
333 | Read <file:Documentation/nbd.txt> for more information, especially | ||
334 | about where to find the server code, which runs in user space and | ||
335 | does not need special kernel support. | ||

468 | If you have a CDROM drive that supports packet writing, say Y to | ||
469 | include preliminary support. It should work with any MMC/Mt Fuji | ||
470 | compliant ATAPI or SCSI drive, which is just about any newer CD | ||
471 | writer. | ||
472 | |||
473 | Currently only writing to CD-RW, DVD-RW and DVD+RW discs is possible. | ||
474 | DVD-RW disks must be in restricted overwrite mode. | ||
