    SubjectSome notes on 2.1.5
    Date
    I got 2.1.5 today, and - after some changes - it compiles and runs on
    my system.

    Sound (i use a SB16) is still broken (some get/put_user problems still
    exist), not really a big problem.

    ppp.c does not compile (due to some forgotten memcpy_fromfs/memcpy_tofs
    calls). I changed them (according to Linus' explantations with the
    2.1.4 patch) to copy_from_user and copy_to_user calls, and it _seems_
    to work, but my changes may be completely nonsense :) (NOTE: i'am not a
    kernel hacker, I'am only carefully reading linux-kernel).

    Introduced with 2.1.3 (i think), the current kernel still breaks the
    rpm tool. I have no idea why, but rpm bombs out while unpacking an
    archive. I performed a strace on rpm (output see below), and I think,
    there is something wrong with the pipes, but it also may be a bug in
    rpm itself (it works fine with 2.0.22).
