From a89f73ed56305c527ff98847d7a2156e355af4ae Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 7 Jun 2023 15:13:35 -0700 Subject: [PATCH] scripts/gdb: fix SB_* constants parsing commit 6a59cb5158bff13b80f116305155fbe4967a5010 upstream. --0000000000009a0c9905fd9173ad Content-Transfer-Encoding: 8bit After f15afbd34d8f ("fs: fix undefined behavior in bit shift for SB_NOUSER") the constants were changed from plain integers which LX_VALUE() can parse to constants using the BIT() macro which causes the following: Reading symbols from build/linux-custom/vmlinux...done.
