Baolin Wang a62ca3f40f mm: change to return bool for ptep_test_and_clear_young() ...

Patch series "change young flag check functions to return bool", v2.

This is a cleanup patchset to change all young flag check functions to
return bool, as discussed with David in the previous thread[1].  Since
callers only care about whether the young flag was set, returning bool
makes the intention clearer.  No functional changes intended.


This patch (of 6):

Callers use ptep_test_and_clear_young() to clear the young flag and check
whether it was set.  Change the return type to bool to make the intention
clearer.
