*
* libmultipath ABI (libmpathutil part)
*
* libmultipath doesn't have a stable ABI in the usual sense. In particular,
* the library does not attempt to ship different versions of the same symbol
* for backward compatibility.
*
* The ABI versioning only serves to avoid linking with a non-matching ABI, to
* cut down the set of exported symbols, and to describe it.
* The version string is LIBMULTIPATH_$MAJOR.$MINOR.$REL.
*
* Policy:
*
* * Bump $MAJOR for incompatible changes, like:
* - symbols removed
* - parameter list or return values changed for existing functions
* - externally visible data structures changed in incompatible ways
* (like offsets of previously existing struct members)
* In this case, the new version doesn't inherit the previous versions,
* because the new library doesn't provide the full previous ABI anymore.
* All predecessors are merged into the new version.
*
* * Bump $MINOR for compatible changes, like adding symbols.
* The new version inherits the previous ones.
*
* * Bump $REL to describe deviations from upstream, e.g. in
* multipath-tools packages shipped by distributions.
* The new version inherits the previous ones.
*/
/*
* Symbols exported by both libmpathutil and libmultipath
* libmpathutil exports just dummy symbols, intended to be overridden
* by those in libmultipath.
* CAUTION - the version in libmpathutil.version and libmultipath.version
* must be THE SAME, otherwise the overriding will fail!
