[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().
