See section 4 on 
http://www.kerneltraffic.org/kernel-traffic/kt20010514_118.html about 
file system limits.

It says that EXT2_LINK_MAX is just one of the reasons why there cannot 
be more than about 32,000 *subdirectories* per directory, and that 
having millions of *files* in a directory is not an issue (other than 
performance). (EXT2_LINK_MAX does not control directory size. 
Directories are just normal files at the file system level.)
