If it's a mountpoint, won't it be in the dcache already? So a purely dcache-based lookup would find it, without having to call through to the file system's ->lookup() method on a dcache miss? And to generate the file handle, all you need in the common case is i_generation? You don't need to pull every inode into core. -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
