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/ v2 -> v3: - Dropped "mm: zswap: calculate limits only when updated" patch after discussions with David Hildenbrand about the complexity of adding notifiers for totalram_pages changes. - Restored "mm: zswap: refactor limit checking from zswap_store()" to the v1 version, and addressed Johannes's comment about deferring the call to zswap_accept_thr_pages() to avoid the division when not needed. Consequently, dropped the Ack and Review tags from v2. - Added a separate comment header for same-filled pags in patch 2. - Collected Acks and Review tags (thanks!). - Rebased on top of the latest mm-unstable. v2: https://lore.kernel.org/lkml/20240405053510.1948982-1-yosryahmed@xxxxxxxxxx/ Yosry Ahmed (4): mm: zswap: always shrink in zswap_store() if zswap_pool_reached_full 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 mm/zswap.c | 98 +++++++++++++++++++++++------------------------------- 1 file changed, 41 insertions(+), 57 deletions(-) -- 2.44.0.683.g7961c838ac-goog
