Subject: Fix early termination of cpu id string
X-Git-Tag: fio-2.1.6~36
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=81fa6e06408879509e005cbb192205b9125f7614

Fix early termination of cpu id string

Commit 2d60ad8e terminated the cpu id string at 12 chars,
but the output from cpuid is 12 chars. So we need one more
character, if we want it null terminated and strcmp()
working.
