Why does Cygwin always use absolute paths instead of OBJECT_ATTRIBUTES.RootDirectory?

[Dan Shelton]

Hello,

Why does Cygwin always use absolute paths instead of
OBJECT_ATTRIBUTES.RootDirectory in NtOpenFile(),
NtSetInformationFile() for rename and hardlinks

This slows down Cygwin path lookups a lot, and with lots of path
elements each lookup with a relative RootDirectory might be a lot
faster, e.g. for openat(), linkat(), renameat().
