Hello, Patches 1,2: Are a resend, I've incorporated them to the set, based on Manfred's comments. Patch 3: is a trivial function rename. Patches 4,5: are attempts to order how Linux ipc deals with EIDRM and EINVAL return error codes. By looking at corresponding manpages two possible inverted return codes are returned, these patches make the manpages accurate now -- but I may have missed something, and we are changing semantics. afaik EIDRM is specific to Linux (other OSes only rely on EINVAL), which is already messy, so lets try to make this consistent at least. Passes all ipc related ltp tests. Thanks!
