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
