+Subject: f2fs: Add inline to f2fs_build_fault_attr() stub
+
+From: Nathan Chancellor <nathan@kernel.org>
+
+commit 0d8968287a1cf7b03d07387dc871de3861b9f6b9 upstream.
+
+When building without CONFIG_F2FS_FAULT_INJECTION, there is a warning
+from each file that includes f2fs.h because the stub for
+f2fs_build_fault_attr() is missing inline:
+
+ In file included from fs/f2fs/segment.c:21:
+ fs/f2fs/f2fs.h:4605:12: warning: 'f2fs_build_fault_attr' defined but not used [-Wunused-function]
+ 4605 | static int f2fs_build_fault_attr(struct f2fs_sb_info *sbi, unsigned long rate,
+ | ^~~~~~~~~~~~~~~~~~~~~
+
+Add the missing inline to resolve all of the warnings for this
+configuration.
