Lets see... Attached is a first shot to get /compat/linux/usr/bin/ipcs -s working. I extended sem.h for SEM_STAT and gave it a special handling in __semctl() to accept a index number. Please review and commmit if acceptable. BTW: In sysv_*.c the sysctls got extended to be tunables. This left the question how (readonly)sysctl vars should get initialised in modules. FE: semmni is currently readonly and used on modload time to allocate a scruct. Because the sysctl var doesn't exist before modload but is used during modload there is no possibility to preset the value except on compile-time. One sollution is to use tunables but can they be changed after startup? BTW2: Is it possible that changing a sysctl(from userland) var calls a kernel function (maybe for sanity checks)? Or has the sysct to be of the type SYSCTL_PROC?
