Subject: [PATCH v2 00/15] treewide: Refactor heap related implementation
Date: Wed, 20 Mar 2024 22:54:02 +0800	[thread overview]
Message-ID: <20240320145417.336208-1-visitorckw@gmail.com> (raw)

This patch series focuses on several adjustments related to heap
implementation. Firstly, a type-safe interface has been added to the
min_heap, along with the introduction of several new functions to
enhance its functionality. Additionally, the heap implementation for
bcache and bcachefs has been replaced with the generic min_heap
implementation from include/linux. Furthermore, several typos have been
corrected.

Changes in v2:
- Add attribute __always_unused to the compare and swap functions
  that do not use the args parameter.
- Rename min_heapify() to min_heap_sift_down().
- Update lib/test_min_heap.c to use min_heap_init().
