f2fs: Add inline to f2fs_build_fault_attr() stub
[ Upstream commit 0d8968287a1cf7b03d07387dc871de3861b9f6b9 ] Fix CVE: CVE-2024-42160 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.
