I have looked around for the patches and I found the following patches
[PATCH v4 07/13] kfifo: provide noirqsave variants of spinlocked in and out helpers
[PATCH v4 08/13] kfifo: provide kfifo_is_empty_spinlocked()
dated on 24 Dec 2019.
Both seems to be okay. The patch is non intrusive to KFIFO adding only
spinlock wrapper functions for the contemporary kfifo functions.
