Subject: [PATCH] slub: __kmalloc_node_track_caller should trace kmalloc_large_node case
Date: Thu, 8 Apr 2010 17:26:44 +0800 [thread overview]
Message-ID: <1270718804-27268-1-git-send-email-dfeng@redhat.com> (raw)
commit 94b528d (kmemtrace: SLUB hooks for caller-tracking functions)
missed tracing kmalloc_large_node in __kmalloc_node_track_caller. We
should trace it same as __kmalloc_node.
