Subject: [PATCH] docs: gdbmacros: print newest record
Git-commit: f2e4cca2f670c8e52fbb551a295f2afc9aa2bd72
Patch-mainline: v6.3-rc1
References: git-fixes
@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.
Fixes: e60768311af8 ("scripts/gdb: update for lockless printk ringbuffer")
