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.)
