Using JFS2, there is no hard limit as far as I know.
There might be some limitations on the number of inodes your filesystem can allocate, although JFS2 can also perform on-demand inode allocation.
From IBM's official documentation:
Quote:
[...] the number of i-nodes available is limited by the size of the file system itself.
Theoretically JFS2 filesystems can support files up to 2 PBs in size. In reality however there's a pseudo-hard limit (the OS will warn you if you try to exceed this limit) set to 32 TB with files no larger than 16 TB.
So, if you were given an infinite amount of disk space under JFS2 it would be possible to have an infinite amount of files as long as the sum of their size did not exceed 2 PBs.
This means you still won't be able to store the whole Internet in your system.
EDIT: And yes, to the eyes of the OS, a directory is still a file.

getdtablesize(2) System Calls Manual getdtablesize(2)
NAME
getdtablesize() - get the size of the per-process file descriptor table
SYNOPSIS
DESCRIPTION
The function returns the maximum number of file descriptors that can currently be stored in a process' file descriptor table. This maximum
number is also known as the soft limit for open files, and can be adjusted up to the hard limit by calling The entries in the descriptor
table are numbered with small integers starting at 0 (zero).
The function returns the total number of file descriptors that a process can have open simultaneously. Each process is limited to a cur-
rent maximum (soft limit) and a fixed upper bound (hard limit) of open file descriptors. This limit is at least 32. The system-defined
limits are configurable. See the descriptions of the and kernel parameters in maxfiles_lim(5) and maxfiles(5), respectively, for informa-
tion about changing the system-defined, per-process limit on open file descriptors.
RETURN VALUES
The function returns the size of the descriptor table (soft limit), and is always successful.
