Subject: [PATCH 10/16] tracing: fix stack tracer header
Date: Thu, 12 Mar 2009 22:37:14 -0400 [thread overview]
Message-ID: <20090313023826.906365262@goodmis.org> (raw)
In-Reply-To: 20090313023704.971438367@goodmis.org
[-- Attachment #1: 0010-tracing-fix-stack-tracer-header.patch --]
[-- Type: text/plain, Size: 1400 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
The stack tracer use to look like this:
# cat /debug/tracing/stack_trace
Depth Size Location (57 entries)
----- ---- --------
0) 5088 16 mempool_alloc_slab+0x16/0x18
1) 5072 144 mempool_alloc+0x4d/0xfe
2) 4928 16 scsi_sg_alloc+0x48/0x4a [scsi_mod]
Now it looks like this:
# cat /debug/tracing/stack_trace
Depth Size Location (57 entries)
----- ---- --------
0) 5088 16 mempool_alloc_slab+0x16/0x18
1) 5072 144 mempool_alloc+0x4d/0xfe
2) 4928 16 scsi_sg_alloc+0x48/0x4a [scsi_mod]
