From 46c92169bd7412aca5b13a9b4a1bc5a609953315 Mon Sep 17 00:00:00 2001 From: John Ogness Date: Thu, 29 Dec 2022 14:49:39 +0106 Subject: [PATCH] docs: gdbmacros: print newest record commit 5d6603be6be1655bf32e3d7d971c697f35803240 upstream. @head_id points to the newest record, but the printing loop exits when it increments to this value (before printing). Exit the printing loop after the newest record has been printed. The python-based function in scripts/gdb/linux/dmesg.py already does this correctly.
