more examples of SYMBOL rip offs.

2.6.0-test5

./kernel/exit.c

static inline void __exit_fs(struct task_struct *tsk)
{
        struct fs_struct * fs = tsk->fs;

        if (fs) {

                __put_fs_struct(fs);
        }
}

void exit_fs(struct task_struct *tsk)
{
        __exit_fs(tsk);
}

./kernel/fork.c

static inline struct fs_struct *__copy_fs_struct(struct fs_struct *old)
{
        struct fs_struct *fs = kmem_cache_alloc(fs_cachep, GFP_KERNEL);
        /* We don't need to lock fs - think why ;-) */
        if (fs) {
                atomic_set(&fs->count, 1);
                fs->lock = RW_LOCK_UNLOCKED;
                fs->umask = old->umask;
                read_lock(&old->lock);
                fs->rootmnt = mntget(old->rootmnt);
                fs->root = dget(old->root);
                fs->pwdmnt = mntget(old->pwdmnt);
                fs->pwd = dget(old->pwd);
                if (old->altroot) {

                        fs->altroot = dget(old->altroot);
                } else {

                read_unlock(&old->lock);
        }
        return fs;
}

struct fs_struct *copy_fs_struct(struct fs_struct *old)
{
        return __copy_fs_struct(old);
}

EXPORT_SYMBOL_GPL(exit_fs);
EXPORT_SYMBOL_GPL(copy_fs_struct);

This is what the issue is about!
Taking away the functionality of the API.

So much for choice anymore.
