Subject: [PATCH 0/3] Enhance min heap API with non-inline functions and optimizations
Date: Mon, 14 Oct 2024 02:47:00 +0800 [thread overview]
Message-ID: <20241013184703.659652-1-visitorckw@gmail.com> (raw)
Add non-inline versions of the min heap API functions in lib/min_heap.c
and updates all users outside of kernel/events/core.c to use these
non-inline versions. Additionally, it micro-optimizes the efficiency of
the min heap by pre-scaling the counter, following the same approach as
in lib/sort.c. Documentation for the min heap API has also been added
to the core-api section.
Regards,
Kuan-Wei
