Documentation about the Virtual File-System

Documentation about the Virtual File-System

[Guillermo López Alejos]

Hi,

This is the first time I post to this mailing list.

I am working with the Computer Architecture department of my
University (Carlos III of Madrid, Spain). I have to adapt an existing
(distributed) filesystem to the Linux kernel. Therefore, I am looking
for the interfaces in the Virtual File-System.

I do not know if this is the correct mailing list to post to about
this topic. If not, please, tell me.

I have read some documentation, but I have not found any reference to
the 2.6 kernel:
    - http://www.linux.it/~rubini/docs/vfs/vfs.html
    - http://www.faqs.org/docs/kernel_2_4/lki.html#toc3
    - http://www.cse.unsw.edu.au/~neilb/oss/linux-commentary/vfs.html

I cannot determine if this references are up-to-date, because I have
not started coding yet. In case they are not, do anyone knows about
newer references?

Is there any "Building a File system HOWTO"?

Thanks in advance,

Regards,

I am not aware of such document but take a look at fs/ramfs/inode.c.
It is a simple memory-based filesystem and sort of a tutorial to the
VFS.

Did you try http://lxr.linux.no/source/Documentation/filesystems/vfs.txt

BTW, on a similar note can somebody recommend some simple sample code
on block IO?

try reading the code to Minix FS, it is simple and will demonstrate
the interfaces you need to present to VFS, and the block interface to
access the disk.  The page interface is preferred over the block
interface recently, expecially for high performance work, but FS's
that use it are more complex and harder to understand (reiserfs, xfs,
ext3).

Get Robert Love's kernel programming book, it has just barely enough
VFS documentation to get you started learning the current interfaces.
