Subject: [PATCH] powerpc/xmon: symbol lookup length fixed
Date: Thu, 24 Oct 2024 02:52:26 +0530 [thread overview]
Message-ID: <20241023212225.1306609-2-mchauras@linux.ibm.com> (raw)
Currently xmon cannot lookup symbol beyond 64 characters in some cases.
Fix this by using KSYM_NAME_LEN instead of fixed 64 characters.
