I want Linux source code for FAT file system in user readable form not in binary form
 

Iam aiming to configure the Linux kernel such that the Fat filesystem support is disabled in it.Then I have to write the Fat file system module and load it into the kernel so that it now recognizes FAt files.So for this purpose I want the FAT file system module code used in Linux ,not in binary form to install but in user readable form(C coding I suppose) to read and understand.Could you please tell me where to find what Iam looking for.

i don't realy understand why you'd do it that way...

you can download the sources at www.kernel.org. Unzip/tar them to any directory (historicaly they belong in /usr/src/linux/.....)
I think the files you are looking for are in /usr/src/linux/fs/fat

Am I missing something? This is exactly what loadable modules do already.

thanx

I found a few PDF files with a (very) detailed explanation of how the FAT filesystem works. If you look for the FIRE distro (forensics) it should be there.

thanx
