[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] tools: delete gtraceview and gtracestat
There has not been any substantial update to them since 2011. My quick
check shows that they don't work.
Just delete them. It would be easy to resurrect them from git log should
people still need them.
