For SysV semaphores, the semmni value is the last part of the 4-element
sem number array. To make semmni behave in a similar way to msgmni and
shmmni, we can't directly use the _minmax handler. Instead, a special
sem specific handler is added to check the last argument to make sure
that it is limited to the [0, IPCMNI] range. An error will be returned
if this is not the case.
Sorry my time has run out, and will be on vacation until July 10th. If
this can wait until then then great, otherwise hopefully Kees can take
a look. It would be wonderful to get Eric's review on this as well.

Thanks for the review. I will try to get other reviewer to chime in.

Kees and Eric, do you have comments on this patchset?

Cheers,
Longman
