It depends on the release, but generally, symbols used by external
modules must be kept fixed. However, various subsystems (libata, wireless)
may change.

With the exception of very specific things (the wireless-tools things
mentioned, which caused its own headaches), the userspace library ABI
is considered pretty much sacrosanct.
