Which feature are you concerned over, the additional hook or the new module? The module is a no-op for anybody who doesn't want it. I can't vouch for the number of users of this module although I've seen some positive feedback from users. One nice bit is that it goes a way towards helping vserver which does have quite a few users. This module really demonstrates one of the points of LSM...to support multiple security models. thanks, -chris -- Linux Security Modules http://lsm.immunix.org http://lsm.bkbits.net - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
