Mateusz Guzik 0573d0a9b8 vfs: add realpathat syscall ... realpath(3) is used a lot e.g., by clang and is a major source of getcwd and fstatat calls. This can be done more efficiently in the kernel. This works by performing a regular lookup while saving the name and found parent directory. If the terminal vnode is a directory we can resolve it using usual means. Otherwise we can use the name saved by lookup and resolve the parent. See the review for sample syscall counts.
