	Seems to be the only way to find the dentry struct associated to an inode, 
in newer kernels most of the functions modified in this patch already receives 
a dentry instead of a raw inode, but for the remaining cases something needs 
to be tailored. I failed to find any macro to help with this endeavour.

	Thanks!
