I looked more closely at this, and although EXDEV is checked for in one place (early in the rename syscall), there are other paths to iop->cifs_rename (nfs server and cachefiles for example call vfs_rename directly) which do not check this, so it looks like the cifs EXDEV check is not redundant and should be kept. -- Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
