Subject: [PATCH v3 0/9] objtool/klp: sympos/module/alternative/etc fixes
Date: Fri,  7 Aug 2026 14:37:45 -0700	[thread overview]
Message-ID: <cover.1786138493.git.jpoimboe@kernel.org> (raw)

v3:
- remove "size = 0" and add comments to create_fake_symbols()
- add patches 8 & 9

v2: https://lore.kernel.org/cover.1785939903.git.jpoimboe@kernel.org
- rebased on tip/master (first 6 patches were merged)
- dropped original patches 7-8 (will post followup)
- added .klp.symid fix

v1: https://lore.kernel.org/cover.1785727106.git.jpoimboe@kernel.org

This consolidates fixes for the klp-build issues reported by Joe over
the last several weeks, plus some more things I found while
testing/reviewing.

  objtool/klp: Allow new references to module exports
