Daniel Verkamp e74864b7a6 kernel_cmdline: remove capacity from Cmdline 
Rather than checking and re-checking the capacity on every insert, just
check the final length of the string when the command line is finished.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
