file system writes

[jenn <sirpj@ecs.csus.edu>]

Hello,

I had a question I hoped someone could answer.

I am modifying reiserfs code. I have added code to the fs that writes
kernel data to a file on the same system. On mount, I make a file by
creating a dentry, and then calling i_op->create. I then release the
dentry. Everything appears to work fine I can see the file on the system
and open it etc... 

I try to write data to this file after creating it like this: 

I make a file pointer
I call filp_open with the name of the file
I call set_fs (to tell it it is a kernel address)
I call fp->f_op->write 
I call filp_close

The write operation returns successfully but no data appears in the
file. I open it and it is empty. It does work if I try to write to a
file on another system though... like I can write to etc/ or /opt.

Brahhhh...

If anyone has some ideas thanks!
