# BUG: The definitions of errno are not defined in the 9P2000.L
# protocol spec, and Linux kernel errno values vary by architecture.
# Most architectures share a "generic" list, but a handful (as of
# Linux v6.14, Alpha, MIPS, PA-RISC, PowerPC, and SPARC) have their
# own numbers.  This IDL file lists the generic numbers.
