Would it not be better to have something akin to
void seq_set_buffer(struct seq_file *m, void *ptr, size_t size)
{
m->buf = ptr;
m->size = size;
m->private = 1;
}
and let the caller simply provide a buffer by any means it wishes (even
statically) and free it again itself. That keeps the caller fully in
control when it wishes to be.
