[PATCH v2 4/7] util/fifo8: Rename fifo8_peek_buf() -> fifo8_peek_constbu


From: Philippe Mathieu-Daudé
Subject: [PATCH v2 4/7] util/fifo8: Rename fifo8_peek_buf() -> fifo8_peek_constbuf()
Date: Mon, 22 Jul 2024 18:07:42 +0200

Since fifo8_peek_buf() return a const buffer (which points
directly into the FIFO backing store), rename it using the
'constbuf' suffix. This will help differentiate with methods
*copying* the FIFO data.
