Exit probe

[Hien Nguyen]

Hi,

Here's the prototype for the exit probe. It did not address the two 
issues that Will raised in the meeting yesterday (locking, and multiple 
probe for the same entry).

The attached files are

1. kernel-2.6.10-rprobe.patch - The exit probe patch.

2. testrprobe.c - This is the test module, when load it will insert a 
rprobe for any function entry address given by the entryaddr parameter 
when loading (ie "insmod testrprobe.ko entryaddr=0xc0abd3456).

3. loadtestrprobe.sh - use this script to load testrprobe module above, 
it will grep out the entry address for the test_erprobe2 function and 
use it  as entryaddr parameter.

4.  calltest2.c - This module symply invoke test_erprobe2 function when 
it is removed.


Thanks, Hien.
