NAME
vref — increment the use count for a vnodeDESCRIPTION
Increment the v_usecount field of a vnode.- vp
- the vnode to increment
Each vnode maintains a reference count of how many parts of the system are using the vnode. This allows the system to detect when a vnode is no longer being used and can be safely recycled for a different file.
Any code in the system which is using a vnode (e.g. during the operation of some algorithm or to store in a data structure) should call vref().
