Defined at line 24 of file ../../src/storage/lib/vfs/cpp/ref_counted.h

VnodeRefCounted implements a customized RefCounted object.

It adds an additional method, "ResurrectRef", which allows Vnodes to be re-used after a reference

count of zero has been reached.

void ResurrectRef ()

This method should only be called if the refcount was "zero", implying the object is currently

executing fbl_recycle. In this case, the refcount is increased by one.

This method may be called to prevent fbl_recycle from following the typical path of object

deletion: instead of destroying the object, this function can be called to "reset" the

lifecycle of the RefCounted object to the initialized state of "ref_count_ = 1", so it can

continue to be utilized after there are no strong references.

This function should be used EXCLUSIVELY from within fbl_recycle. If other clients (outside

fbl_recycle) attempt to resurrect the Vnode concurrently with a call to Vnode::fbl_recycle,

they risk going through the entire Vnode lifecycle and destroying it (with another call to

Vnode::fbl_recycle) before the initial recycle execution terminates.
