proc_mkdir -> where is proc_rmdir ?

proc_mkdir -> where is proc_rmdir ?

[Lukas Ruf]

Dear all,

I created some directories below /proc while a module got installed.
When I de-install the module, I would like to remove these directories as
well?

First, I remove the entries within the directory by remove_proc_entry().
So, the directories are empty.  But when I try to remove the self-created
directories with a similar call to remove_proc_entry(), nothing happens.

So, I simply ask: is there somewhere a proc_rmdir() ?  If not, how do I
need to call the remove_proc_entry() such that the directory gets removed?

Thanks for any help!

Lukas

Is the target proc directory in use, such as mounted?

remove_proc_entry() is what the usb subsystem uses to remove its
main usb-fs directory (/proc/bus/usb), and it works.

That's also what the proc-fs example at
http://kernelnewbies.org/documents/kdoc/procfs-guide/example.html
uses.  See that document if you haven't already.
