* Only "network" errnos, which are defined below, are allowed on wire (or on
* disk). Generic routines exist to help translate between these and a subset
* of the "host" errnos. Some host errnos (e.g., EDEADLOCK) are intentionally
* left out. See also the comment on lustre_errno_hton_mapping[].
*
* To maintain compatibility with existing x86 clients and servers, each of
* these network errnos has the same numerical value as its corresponding host
* errno on x86.
