From 13dd58cce8d23692e21c9fad3ca41aa19ecc4c82 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 4 Jun 2023 16:56:49 +0200 Subject: [PATCH] bcache: don't pass a stack address to blkdev_get_by_path sb is just an on-stack pointer that can easily be reused by other calls. Switch to use the bcache-wide bcache_kobj instead as there is no need to claim per-bcache device anyway.
