Some architectures don't use socketcall, so they use a separate syscall. IIRC, powerpc is migrating away from socketcall (commit 86250b9d12caa1a3dee12a7cf638b7dd70eaadb6, "powerpc: Wire up direct socket system calls"), hence they added a separate call for it. > However, if your unistd.h has defined __NR_recvmmsg before, you should > probably add it to the syscall table, just in case that someone built > a binary with that number. We never had it. BTW, we have a hole at 218/219. I don't remember why, but it may have been a placeholder for pselect6 and ppoll when that implementation was still in flux. Couldn't find anything about it in git/cvs archives, so I'll check have to check my old mailing list archives...
