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

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@google.com/

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
