In general, none of the kernel synchronization-type functions should have been used in userspace since they often depend on infrastructure which is only in the kernel in order to work properly. The new headers installation system strips out any code intended for kernel use only from the userspace-visible headers. (Not to mention the licensing issues - the kernel is GPL, not LGPL, so only GPL programs could have legally done so in the first place.) -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@...pamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
