Submission notes for the kernel/vb2-dma-resv-rfc series. Captures:
- Pre-flight gates (full-tree compile-test, boot-test on ohm,
runtime validation by uninstalling kwin-fourier and confirming
chrome still plays through, syscall-count delta).
- The git send-email recipe with the full CC list (linux-media,
V4L2 maintainers, hantro maintainer Tomasz Figa, dma-buf
reviewers Sumit Semwal / Christian König / Jason Ekstrand,
dri-devel, linux-rockchip, Heiko / Jeffy).
- Expected reviewer feedback (opt-in vs. auto-on, selftest
request, signal-point semantics for async producers,
Pick-to-LTS decision).
- Withdraw conditions if upstream is already doing this work or
the design has a fundamental issue we didn't see.
This is the third upstream-submission draft in the campaign:
upstream-submissions/qt6-base-fourier/ bugreports.qt.io draft
upstream-submissions/kwin-fourier/ invent.kde.org MR draft
upstream-submissions/vb2-dma-resv/ linux-media draft (this)
