hi.
dont take me for an expert, but:
if ur not writing code to a specific f/s, then no.
these detailed are _supposed_ to be hidden from the vfs's point of view.
however, at the vfs level, u can check if a dentry has some cached 
children -> and by no means u can take that as an authoritive answer...
what u can do, and it is highly recommended to avoid, is to open a 
corresponding file for the inode, and then invoke the file->f_op->readdir 
function. (dont forget, the magik is in the filldir function u pass it...)

anyway, why do you need such a thing????
