VOP_INACTIVE(9) FreeBSD Kernel Developer's Manual VOP_INACTIVE(9) NAME VOP_INACTIVE, VOP_RECLAIM - reclaim file system resources for a vnode SYNOPSIS #include <sys/param.h> #include <sys/vnode.h> int VOP_INACTIVE(struct vnode *vp, struct thread *td); int VOP_RECLAIM(struct vnode *vp, struct thread *td); DESCRIPTION The arguments are: vp The vnode being reclaimed. VOP_INACTIVE() is usually called when the kernel is no longer using the vnode. However, there is no guarantee that it will be called at all, for example if the last reference was dropped while the vnode lock could not be upgraded to exclusive without sleeping. This may be because the reference count reaches zero or it may be that the file system is being forcibly unmounted while there are open files. It can be used to reclaim space on the last close of an `open but deleted' file. VOP_RECLAIM() is called when a vnode is being reused for a different file system. Any file system specific resources associated with the vnode should be freed. LOCKS For both VOP_INACTIVE() and VOP_RECLAIM(), the vp will be exclusively locked on entry, and must be left exclusively locked on return.
