Re: C question

[fiaid@quasi-sane.com]

in the definition of inode in the inode.h file, how are i_mtime, i_ctime, 
and i_atime defined?  it might be that assigning a int to them is not 
possible.  you might need to assign '0', or use NULL.  i don't have a 
linux box handy or i would be more help here.  but it appears that you are 
trying to cross data types when given the anal error checking in kernel 
compiles, it ain't going ot happen.
