I suppose this means that your kernel was compiled with
CONFIG_NFS_DIRECTIO=y? Interesting that it is enabled by default in
Fedora and Debian. The kernel itself recommends not to use it by
default: "This kernel build option defaults OFF to avoid exposing system
administrators unwittingly to a potentially hazardous feature."
