[Crash-utility] Fwd: [PATCH 0/3] trace.so: Make trace dump -t work again
Thanks a lot, Steve -- forwarding to the crash-utility mainling list and to Xu Huan,
the trace.c maintainer for his ACK.
There was a report on this list about the sp_type problem last week, but the proposed fix
(which just changed all module symbol sp_type's to '?' in the crash utility
itself) wasn't
acceptable, and there was no response after that. This looks to fix the same issue.

Subject: [PATCH 0/3] trace.so: Make trace dump -t work again
Hi Dave,
I gave a talk at SCaLE 17x last week and was going to demonstrate using
ftrace on a system that crashes, and then pulling out the vmcore file
with kexec and kdump, and then pulling out the ftrace ring buffers and
creating a trace.dat file with the crash extension trace.so.
Unfortunately, this wasn't working as I planned. I created the
following three patches, where two fix the issue (I was getting a
corrupted trace.dat file), and the third actually documents the '-t'
option of the dump command. Hopefully you can accept these patches.
Thanks!
-- Steve
