From dcc76777c6490c4d40199d0abe0942186d944a51 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 8 Oct 2025 18:08:58 +0300 Subject: [PATCH] btrfs: tree-checker: fix bounds check in check_inode_extref() commit e92c2941204de7b62e9c2deecfeb9eaefe54a22a upstream. The parentheses for the unlikely() annotation were put in the wrong place so it means that the condition is basically never true and the bounds checking is skipped.
