hannken 72439b7dc8 Current support for iterating over mnt_vnodelist is rudimentary. Every 
caller has to care about list and vnode mutexes, reference count being zero,
intermediate vnode states like VI_CLEAN, VI_XLOCK, VI_MARKER and so on.

Add an interface to iterate over a vnode list:

void vfs_vnode_iterator_init(struct mount *mp, struct vnode_iterator **marker)
void vfs_vnode_iterator_destroy(struct vnode_iterator *marker)
bool vfs_vnode_iterator_next(struct vnode_iterator *marker, struct vnode **vpp)

vfs_vnode_iterator_next() returns either "false / *vpp == NULL" when done
or "true / *vpp != NULL" to return the next referenced vnode from the list.

To make vrecycle() work in this environment change it to

bool vrecycle(struct vnode *vp)

where "vp" is a referenced vnode to be destroyed if this is the last reference.

Discussed on tech-kern.

hannken 6935b8d9a0 Update arguments of vrecycle(), description of getnewvnode() and 
the vnode flags.
 2014-02-22 10:08:12 +00:00
hannken 65b1f85ab6 Vnode API cleanup pass 1. 
- Make these defines and functions private to vfs_vnode.c:

  VC_MASK, VC_LOCK, DOCLOSE, VI_IANCTREDO and VI_INACTNOW
  vclean() and vrelel()

- Remove the long time unused lwp argument from vrecycle().

- Remove vtryget(), it is responsible for ugly hacks and doesn't
  look that effective.

Presented on tech-kern.

hannken 1664eae7f3 Using vfinddev() leads to vnode races as it returns an unreferenced 
vnode that may disappear before the caller has a chance to reference it.

Reference the vnode while the specfs cache is locked.

Welcome to 5.99.37.

No objections on tech-kern.
