61 * These are NO-OPS for BSD until Isilon upstreams EXITCODE support.
62 * EXITCODE is an in-memory ring buffer that holds the routines failing status.
63 * This is a valuable tool to use when debugging and analyzing issues.
64 * In addition to recording a routine's failing status, it offers
65 * logging of routines for call stack tracing.
66 * EXITCODE should be used only in routines that return a true errno value, as
67 * that value will be formatted to a displayable errno string. Routines that
68 * return regular int status that are not true errno should not set EXITCODE.
69 * If you want to log routine tracing, you can add EXITCODE(0) to any routine.
70 * NFS extended the EXITCODE with EXITCODE2 to record either the routine's
71 * exit errno status or the nd_repstat.
