Stephen Tweedie gave a talk back in 2000 which covered revoke records. There's a transcript of his talk here: http://olstrans.sourceforge.net/release/OLS2000-ext3/OLS2000-ext3.html The link to the audio file of the talk is dead, but I managed to find a copy of the mp3 file on Google. To make sure it doesn't get lost I've made a copy of it. The original and the copy can be found at: http://ftp.gnumonks.org/pub/congress-talks/ols2000/high/cd1/2000-07-20_15-05-22_A_64.mp3 ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/presentations/2000-07-20_15-05-22_A_64.mp3 - Ted
