#53192 — Bug#818087: Blacklist/whitelist kernel module ABI symbols in advance

[Multipart message — attachments visible in raw view] — view raw

Package: src:linux
Severity: wishlist

Currently we attempt to maintain the kernel module ABI within each
stable release, and try to avoid ABI bumps within unstable other than
for new upstream releases.

Sometimes we decide that an ABI change can be ignored (i.e. we allow it
to change withut bumping the ABI number) because it is not intended for
use by out-of-tree modules, only for specific modules built from the
kernel.  However we do this reactively, rather than in advance.

We could serve out-of-tree module users and packagers better if we
implemented a blacklist or whitelist of unstable symbols and made
modpost warn when they are used.

If at first you don't succeed, you're doing about average.
