Linux md driver source

[Judy Brock]

Hello,

Is the source code for the Linux md driver (ie Software RAID) open
source and if so, where exactly is it (what URL)?

I've tried to find it on kernel.org but not having any luck - am new
to Linux and open source (background is Windows storage driver dev).

thanks in advance,

Judy

It is in the kernel source tree, under drivers/md

Download the Linux you wish to hack (say - linux-2.6.31.5 or whatev - can
be found on http://www.kernel.org ), unpack it and look in those unpacked
sources.

Of course it is. It's in the mainline kernel.

In the kernel tree, the directory .../drivers/md/

There are 79 .c and .h files in there, so depending on just what you
really want to know you may have some further searching to do....

Install the kernel source for your distro, then look at
/usr/src/linux-2.6.31.5-1mnb/drivers/md/md.c
replacing the linux version number as appropriate.
