How to add VFS support to the Linux 2.4 kernel

[Steven E. Protter]

I have a customer that wishes to add VFS suppor to the 2.4 kernel on a RedHat box.

I'm not completely clear what the steps are.

What I need to do is:
1) Install VFS support.
2) If needed, recompile the kernel.

Basically I need a cookbook.

Hers is what I have so far and I don't think its enough.

This is extrange, I was sure that VFS was in the kernel 2.4 by default:

http://www.faqs.org/docs/kernel_2_4/lki-3.html

VFS is not another thing but using the same command to perform operations on differents file systems type, for example if you run mkfs, the -t option will call the correct mount command:

mkfs -t ext3
mkfs.ext3
mkfs -t vfat
mkfs.vfat

And so on.

It may be, perhaps the internal customer is not correct.

What I may need is a simple guide as to how to use VFS, which I may have already found.

It would be nice to be sure, hence the thread.

Please confirm to earn a double bunny. I need proof.

The last document describes the vfs interface (as present in Linux 2.3.29).
