Why not figure out a way to embed the tapsets > into the kernel source (a.l.a Docbook)? Sure, why not. The only problem is to come up with a notation which isn't too invasive. Frank's example showed one problem tapsets are supposed to solve: make parameters available under a name which doesn't change. Another goal for them is to make commonly used expressions derived from the state when entering the function available (e.g., inode belonging to a file descriptor). This kind of information might need a single line for each convenience variable defined in the tapset. So, it should be manageable. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkhsIMoACgkQ2ijCOnn/RHThzgCeMIIR9KnHvgygE5/cCTdQfwfK 1u8AnAy9iqIb7XzgzWifMG0aWlZATjHR =hNt1 -----END PGP SIGNATURE-----
