Subject: perf machine: Fix id_hdr_size initialization
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=14bd6d20fef603060474701967085442b716b6a9;p=deliverable%2Flinux.git

perf machine: Fix id_hdr_size initialization

The id_hdr_size field was not properly initialized, set it to zero, as
the machine struct may have come from some non zeroing allocation
routine or from the stack without any field being initialized.
