IPC Semaphores Parameters

If no one on the system uses or plans to use IPC semaphores, you may want to consider excluding this module.

The following tunable parameters are associated with interprocess communication semaphores (see the semctl(2) reference page):

semmni - specifies the maximum number of semaphore identifiers in the kernel.
semmns - specifies the number of ipc semaphores system-wide.
semmnu - specifies the number of ''undo'' structures system-wide.
semmsl - specifies the maximum number of semaphores per semaphore identifier.
semopm - specifies the maximum number of semaphore operations that can be executed per semop(2) system call.
semume - specifies the maximum number of ''undo'' entries per undo structure.
semvmx - specifies the maximum value that a semaphore can have.
semaem - specifies the adjustment on exit for maximum value.
