Subject: [PATCH 1/2] dyndbg: fix incorrect mod_ct value in dynamic_debug_init()
Date: Tue, 11 Aug 2026 20:18:30 +0800 [thread overview]
Message-ID: <20260811121831.577848-2-yuntao.wang@linux.dev> (raw)
In-Reply-To: <20260811121831.577848-1-yuntao.wang@linux.dev>
Suppose all `struct _ddebug` instances belong to the same module, mod_ct
should be 1, but it is currently 0.
Fix it.
