class MaybeOpenedVnode
Defined at line 46 of file ../../src/storage/lib/vfs/cpp/vfs.h
A wrapper around a Vnode that may or may not be open (e.g. Vnode returned from `CreateOrLookup`),
ensuring it is closed on destruction unless explicitly taken. This is used by `Vfs::Open` and
`Vfs::DeprecatedOpen` to clean up safely when returning early due to validation failures.

fbl::RefPtr<Vnode> TakeAsOpened ()Takes the vnode. The caller assumes responsibility for closing it. For example, when returning
a successfully opened local node.
Defined at line 93 of file ../../src/storage/lib/vfs/cpp/vfs.h
fbl::RefPtr<Vnode> CloseAndTake ()Closes the vnode if it is open, and returns it. This can be used, e.g., when forwarding a node
to a remote filesystem or transferring it to OpenResult, which expects to manage the open state
itself.
