2007-07-16	fault-injection: fix example scripts in documentation	Akinobu Mita	1	-4/+0
	Fix and cleanup example scripts in fault injection documentation. 1. Eliminate broken oops() shell function. 2. Fold failcmd.sh and failmodule.sh into example scripts. It makes the example scripts work independent of current working directory. 3. Set "space" parameter to 0 to start injecting errors immediately. 4. Use /sys/module/<modulename>/sections/.data as upper bound of .text section. Because some module doesn't have .exit.text section.

2006-12-08	[PATCH] fault injection: documentation and scripts	Akinobu Mita	1	-0/+4
	This patch set provides some fault-injection capabilities. - kmalloc() failures - alloc_pages() failures - disk IO errors We can see what really happens if those failures happen. In order to enable these fault-injection capabilities: 1. Enable relevant config options (CONFIG_FAILSLAB, CONFIG_PAGE_ALLOC, CONFIG_MAKE_REQUEST) and if you want to configure them via debugfs, enable CONFIG_FAULT_INJECTION_DEBUG_FS. 2. Build and boot with this kernel 3. Configure fault-injection capabilities behavior by boot option or debugfs - Boot option failslab= fail_page_alloc= fail_make_request= - Debugfs /debug/failslab/* /debug/fail_page_alloc/* /debug/fail_make_request/* Please refer to the Documentation/fault-injection/fault-injection.txt for details. 4. See what really happens.
