Function names reported in the list contain our ASSERT macro that conditionally calls BUG() that I believe is what could cause the unreachable instructions but I don't see how. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/btrfs/ctree.h#n3113 __cold static inline void assfail(const char *expr, const char *file, int line) { if (IS_ENABLED(CONFIG_BTRFS_ASSERT)) { pr_err("assertion failed: %s, in %s:%d\n", expr, file, line); BUG(); } } #define ASSERT(expr) \ (likely(expr) ? (void)0 : assfail(#expr, __FILE__, __LINE__))
