[PATCH 0/3] Introduce Xen fault injection facility

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series adds a facility, which can be used to instrument Xen code with
fault injections.
It is based "Fault injection capabilities infrastructure" described here:
- Documentation/fault-injection/fault-injection.txt

First patch adds a generic facility to use anywhere in Xen.
When using it all the fault injection user land control directories (if
any) will appear here:
- /sys/kernel/debug/xen/fault_inject/

To distinguish with generic (or core) Xen fault injections, next two
patches add additional directories to the root path above for blkback and
netback drivers respectively:
- /sys/kernel/debug/xen/fault_inject/xen-blkback/
- /sys/kernel/debug/xen/fault_inject/xen-netback/
