From 4a8eabc6e4c7fec44570e9e70d464fea076633c9 Mon Sep 17 00:00:00 2001 From: Sahil Chandna Date: Thu, 5 Feb 2026 00:24:07 +0530 Subject: [PATCH] mm/vmscan: 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.
