src/share/man/man9: namecache.9
src/sys/kern: vfs_cache.c vfs_getcwd.c
Log Message:
Using cache_revlookup() leads to vnode races as it returns an unreferenced
vnode that may disappear before the caller has a chance to reference it.
Reference the vnode while the name cache is locked.
No objections on tech-kern.
