vfs: make d_path() get the root path under RCU
This avoids the spinlocks and refcounts in the d_path() sequence too (used by /proc and various other entities). See commit 8b19e34188a3 for the equivalent getcwd() system call path. And unlike getcwd(), d_path() doesn't copy the result to user space, so I don't need to fear _that_ particular bug happening again. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
