Subject[PATCH 0/3] livepatch: add shadow variable API
Date
This patchset is a simplified livepatch port of kpatch's "shadow"
variable API [1]. The kpatch project has successfully employed such
shadow variables to implement patches that have extended data structure
elements. This API provides livepatch a means of associating new,
shadow data fields with existing data structures.

See the first patch for the implementation, the second for further
documentation (API, conccurency notes, use-case code snippets) and the
third patch for an update to the sample livepatch module using shadow
variables.
