v1 -> v2:
- Following Namhyung's review suggestions, optimize patch 3 by removing
initialization of the return value to true. Instead, use the internal
function's return value directly and add a blank line between the
declaration and other statements.
- Add a blank line before the return statement.
- Following Namhyung's review suggestions, fix the incorrect Fixes tags
for all three patches.
- Link to v1: https://lore.kernel.org/all/20241128125432.2748981-1-quic_zhonhan@quicinc.com/
