This is all certainly doable, but it leaves me with one concern: there will be no signal to external module maintainers that the change needs to be made. So, beyond doubt, quite a few of them will just continue to be shipped unfixed - and they will still run. If any of them actually *need* the BKL, something awful may happen to somebody someday. jon -- 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/ | |||||||||
