New Revision: 285931
URL: https://svnweb.freebsd.org/changeset/base/285931
Log:
Implement directory and FIFO creation.
The file_create() system call can be used to create files of a given
type. Right now it can only be used to create directories and FIFOs. As
CloudABI does not expose filesystem permissions, this system call lacks
a mode argument. Simply use 0777 or 0666 depending on the file type.
