Well that looks like rather a hack.
It would still be a hack, but a better implementation might be to save the procfs superblock's address in a global then do
#ifdef CONFIG_PROCFS static inline bool is_procfs_sb(struct super_block *sb) { return sb == saved_procfs_sb; } #else static inline bool is_procfs_sb(struct super_block *sb) { return false; } #endif
