Subject: mm: delete stale comment about cachelines
Date: Mon, 01 Jun 2026 11:40:09 +0000
These comments have been wrong since commit a211c6550efc ("mm: page_alloc:
defrag_mode kswapd/kcompactd watermarks") added NR_FREE_PAGES_BLOCKS.
Since nobody has complained about it in the last year, it seems unlikely
these comments were particularly useful anyway, so delete them.
