The question was if glibc supports separate ipc syscalls instead of calling sys_ipc.

I look at implementation and for example at sysdeps / unix / sysv / linux / msgctl.c
You can see that for __new_msgctl function is called kernel syscall sys_ipc

 return INLINE_SYSCALL (ipc, 5, IPCOP_msgctl, msqid, cmd, 0, CHECK_1 (buf));

but is possible to call directly sys_msgctl - for blackfin case syscall 334.

And second part of my question was if someone work on it.
