[PATCH] proc.5: /proc/fs is not empty directory

[PATCH] proc.5: /proc/fs is not empty directory

[jchaloup]

Man page for proc says:
/proc/fs
	      Empty subdirectory.

But ls says something else:
$ ls /proc/fs/
ext4  jbd2  nfs  nfsd

In addition from https://www.kernel.org/doc/Documentation/filesystems/proc.txt, caption: 1.9 Ext4 file system parameters:

Information about mounted ext4 file systems can be found in
/proc/fs/ext4.

This patch gives better description for the content. Open to give more description if someone knows more or where to find it.

hi,
exported sounds for me like nfs export. what is about:
"Information about mounted file systems" (copied and ajusted from proc.txt)

Walter's suggestion seems a reasonable place to start. I added the following:

[[
Contains subdirectories that in turn contain files
with information about (certain) mounted filesystems.
]]

Cheers,
