Allow to build cas_cache module in two versions - one for the new cas_bd and one compatible with symvers of running cas_bd. That way we can load new cas_cache with old cas_bd temporarily, allowing for smooth transition between two versions. Signed-off-by: Robert Baldyga <robert.baldyga@unvertical.com>
Introduce upgrade target, which performs in-flight upgrade of cas_cache module. It requires Open CAS to be built with FALLBACK_SYMVERS option pointing at the symvers file of currently loaded cas_bd module. It automatically unloads cas_cache, installs new modules in regular and symvers-compatible versions and loads cas_cache compatible with running cas_bd (transition mode). After unloading both modules or rebooting, the new versions of both modules are loaded automatically. This mechanism is currently limited to the same Open CAS version, so it is usable mostly for development purposes. It opens a path for full in-flight upgrade once metadata migration mechanism is ready. Signed-off-by: Robert Baldyga <robert.baldyga@unvertical.com>
