From 8c599da5060c2bb4c085a7d92794c8134f61ef25 Mon Sep 17 00:00:00 2001 From: Tony Dinh Date: Tue, 26 Aug 2025 12:45:37 -0700 Subject: [PATCH] fs: ext4fs: add CONFIG_EXT4_MAX_JOURNAL_ENTRIES to Kconfig Add maximum ext4 journal entries to Kconfig. It is necessary since the number of journal entries is proportional to disk capacity. For example, an ext4 4TB HDD partition could require approximately 500 entries.
