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.
