Daniel Verkamp a323861bf5 p9: set filetype from directory to file in lcreate 
The 9p lcreate operation takes a directory fid as input and creates a
file in that directory; when the operation completes, the same fid
becomes a reference to the newly-created file. We updated the internal
self.fids structure's file and path fields to point to the new file, but
we neglected to update the filetype field, which would remain as the
original FileType::Directory.

This caused an issue with commit 53cd18e062 ("p9: use *at() functions
for set_attr"), since that change causes set_attr requests to validate
the filetype is not a directory when attempting to set its length.

crosvm - The Chrome OS 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 Chrome OS 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 Chrome OS devices.
