From the changelog, PATH_MAX was being removed in as many places as 
possible.

But for mkdir, we never need to check the size as we're creating the 
filename. Whereas deletion requires the lookup of the inode with 
path2cookie which requires PATH_MAX variable.

As realistically, the kernel itself shouldn't impose limits. It's only 
the filesystem itself which has the limits.
