Here's an excellent resource for that type of question: http://http://lxr.linux.no/linux/ This has a completely cross-referenced index of the kernel source tree, many different versions. Typing rcu_read_lock into the search, shows that it's implemented as an inline function in include/linux/rcupdate.h <http://lxr.linux.no/linux+v2.6.35.4/include/linux/rcupdate.h#L310> Similarly, you can find the definitions for the rest of the functions you're looking for. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
