While working on the POSIX message queue subsystem a while back I noticed some things that could stand to be improved (as it turns out, drastically so). So I improved them. The first patch fixes the POSIX message queue subsystem to not suck under heavy load and high queue depths. The next two are minor touchups/fixes. The fourth is in the tools/selftests directory and is the app I used to do the performance testing of the mqueue subsystem.
Considering that the changes I've made here make as much as a 1000 fold difference in performance, it would be nice to see them go into linux-next ;-)
Special note: these patches require and are built on top of my previous patches. Applying these to a tree that does not also have the previous series of 7 patches I sent related to the mqueue subsystem will result in a broken tree that won't compile.
