From c69ca4e992e3fd08d3d9fb9e498cb11d1c3e21c7 Mon Sep 17 00:00:00 2001 From: Sahil Chandna Date: Thu, 5 Feb 2026 00:24:08 +0530 Subject: [PATCH] mm/zswap: use %pe to print error pointers Use the %pe printk format specifier to report error pointers directly instead of printing PTR_ERR() as a long value. This improves clarity, produces more readable error messages. This instance was flagged by the Coccinelle script (misc/ptr_err_to_pe.cocci) as an opportunity to adopt %pe. Found by: make coccicheck MODE=report M=mm/ No functional change intended.
