Since callers only care about whether the young flag was set, returning bool makes the intention clearer. No functional changes intended. Ran mm selftests on Arm64 and x86 machines, and no issues were found. Note that I only CC'd the arch mailing lists to avoid disturbing too many people. [1] https://lore.kernel.org/all/d172d6bf-c60c-4cf5-9da9-f30de38cdfed@kernel.org/ Changes from v1: - Add reviewed tag from Lorenzo and Ritesh. Thanks. - Drop extern and use 2 tabs indentation, per Lorenzo. - Fix the incorrect conversion of the 'id' variable.
