Its filename was zram-add-pr_fmt-to-backend-files.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Haoqin Huang Subject: zram: add pr_fmt to backend files Date: Tue, 4 Aug 2026 17:38:39 +0800 Add pr_fmt to each backend so that pr_err() messages are auto-prefixed with the algorithm name. While at it, tweak the deflate winbits pr_err to avoid a duplicated "deflate" prefix.
