There's some ongoing work to make seq_buf easier to use: https://lore.kernel.org/lkml/[email protected]/ Perhaps we can add an "alloc" and "free" pair too, to handle this case: > msg = kmalloc(OCX_MESSAGE_SIZE, GFP_KERNEL); > seq_buf_init(&s, msg, OCX_MESSAGE_SIZE); But perhaps it's overkill... -- Kees Cook
