Subject: [PATCH v3 0/2] mm: folio conversion and refactoring in do_swap_page()
Date: Tue, 28 Jul 2026 00:14:29 +0800	[thread overview]
Message-ID: <20260727161431.13455-1-hongfu.li@linux.dev> (raw)

From: Hongfu Li <lihongfu@kylinos.cn>

Convert the device-private migration path in do_swap_page() to use
folio APIs, then extract all non-swap entry handling into a new
do_non_swap_page() helper to improve readability and reduce the
size of the main swap fault function.

Hongfu Li (2):
  mm: Use a folio in the softleaf_is_device_private path
  mm: Extract non-swap entry handling to do_nonswap_softleaf()
