From 693680b9add63dbebb2505a553ff52f8c706c8c0 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Tue, 17 Feb 2026 17:22:44 -0800 Subject: [PATCH] fsverity: fix build error by adding fsverity_readahead() stub hppa-linux-gcc 9.5.0 generates a call to fsverity_readahead() in f2fs_readahead() when CONFIG_FS_VERITY=n, because it fails to do the expected dead code elimination based on vi always being NULL. Fix the build error by adding an inline stub for fsverity_readahead(). Since it's just for opportunistic readahead, just make it a no-op.
