3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * Header file to support the signalfd facility. Note that this facility
3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * is designed to be binary compatible with the Linux signalfd facility, modulo
3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * the signals themselves; values for constants here should therefore exactly
3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * match those found in Linux, and this facility shouldn't be extended
3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * independently of Linux.
3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * To assure binary compatibility with Linux, these values are fixed at their
3d729aecc03ea6ebb9bd5d56b8dccd24f57daa41Jerry Jelinek * Linux equivalents, not their native ones.
