Subject: [PATCH 0/3] Shrink time spent in copy_data_pages()
Date: Mon, 18 May 2026 17:34:21 -0400 [thread overview]
Message-ID: <20260518-hibernation-decrease-time-in-copy-data-pages-v1-0-3998bdf90ee5@collabora.com> (raw)
This series shrinks the time spent in copy_data_pages(). Patches 1 and 2
are to ease debugging the time spent in that function, while patch 3
does the actual work to allow it to be shorter - based on a module
parameter since it has drawbacks for uncompressed hibernation images.
