[PATCH v2 0/3] Optimization and alignment for MMC, Rust and iwlwifi
From: Adrian Garcia Cicuelo
Date: Sun Mar 15 2026 - 13:18:27 EST
This patch series provides functional optimizations and alignments for
multiple kernel components, specifically targeting MMC quirks,
Rust block driver abstractions, and iwlwifi interrupt affinity.
These changes were previously submitted as a single monolithic patch
but have now been split into logical, atomic commits as requested.
The code style has been verified against checkpatch.pl.
Summary of changes:
1. MMC: Consolidate imx25/35 quirk data and add Kingston CID support.
2. Rust: Update rnull driver to use Pin<KBox<QueueData>> for alignment
with kernel 7.0 zero-copy initialization.
3. iwlwifi: Optimize MSI-X interrupt affinity mapping by skipping
the boot core (CPU0) for high-rate RSS queues.
v1 -> v2:
- Split monolithic patch into logical commits.
- Removed accidental addition of nested kernel repository.
- Fixed Rust code style (line wrapping).
- Fixed iwlwifi white space issue.
- Wrapped commit descriptions to 75 characters.
