[PATCH] Linux Kernel Dump Test Module
A simple module to test Linux Kernel Dump mechanism. This module uses jprobes to install/activate pre-defined crash points. At different crash points, various types of crashing scenarios are created like a BUG(), panic(), exception, recursive loop and stack overflow. The user can activate a crash point with specific type by providing parameters at the time of module insertion. Please see the file header for usage information. The module is based on the Linux Kernel Dump Test Tool by Fernando <http://lkdtt.sourceforge.net>. This module could be merged with mainline. Jprobes is used here so that the context in which crash point is hit, could be maintained. This implements all the crash points as done by LKDTT except the one in the middle of tasklet_action().
