[PATCH v2 0/5] zswap same-filled and limit checking cleanups

From: Yosry Ahmed
Date: Fri Apr 05 2024 - 01:35:26 EST


Miscellaneous cleanups for limit checking and same-filled handling in
the store path. This series was broken out of the "zswap: store
zero-filled pages more efficiently" series [1]. It contains the cleanups
and drops the main functional changes.

[1]https://lore.kernel.org/lkml/20240325235018.2028408-1-yosryahmed@xxxxxxxxxx/

v1 -> v2:
- Dropped the patch to skip limit checking for same-filled pages.
- Added a patch to calculate limits in pages only when they change, as
suggested by Johannes.

Yosry Ahmed (5):
mm: zswap: always shrink in zswap_store() if zswap_pool_reached_full
mm: zswap: calculate limits only when updated
mm: zswap: refactor limit checking from zswap_store()
mm: zswap: move more same-filled pages checks outside of zswap_store()
mm: zswap: remove same_filled module params
