Subject: [PATCH 0/3] Introduce Xen fault injection facility
Date: Fri, 20 Apr 2018 10:47:20 +0000	[thread overview]
Message-ID: <20180420104603.17823.31095.stgit@dev-dsk-staskins-1a-ca5afbf2.eu-west-1.amazon.com> (raw)

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/

---

      xen: add generic fault injection facility

      xen blkback: add fault injection facility
