From 63ad216fbfe2240da67233e0a0d10af8a12f7bde Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Thu, 18 Dec 2025 12:21:45 +0100 Subject: [PATCH] fs: Replace simple_strtoul with kstrtoul in set_ihash_entries Replace simple_strtoul() with the recommended kstrtoul() for parsing the 'ihash_entries=' boot parameter. Check the return value of kstrtoul() and reject invalid values. This adds error handling while preserving behavior for existing valid values, and removes use of the deprecated simple_strtoul() helper.
