At the moment, the names of these DSOs are different: x86: linux-vsyscall.so.1 ia64: linux-gate.so.1 I think there is some value in using the same name on all platforms that support such a DSO. vsyscall makes no sense for ia64, since there are no virtual syscalls (instead, ia64 linux provides a fast system call convention which, when coupled with light-weight system call handlers, provide full syscall semantics at more or less the speed of virtual system calls). Not surprisingly, I like the name "linux-gate", since that is really what this DSO is all about: it's a gateway between user and kernel space. However, if this name isn't appropriate for x86, perhaps we can find another name which will be acceptable to everybody. I already checked with Roland McGrath (cc'd), and he agrees that a common name would be good and said that he doesn't care about the particular name that will be used. Does anyone have any strong feelings about this? If not, I plan to submit a patch to rename the x86 DSO to linux-gate.so.1. Thanks, --david
