Module Name:    src
Committed By:   hannken

Modified Files:
        src/sys/fs/msdosfs: denode.h msdosfs_denode.c msdosfs_lookup.c
            msdosfs_vfsops.c msdosfs_vnops.c msdosfsmount.h

Log Message:
Change msdosfs from hashlist to vcache:
- Use (dir_cluster, dir_offset, dir_generation) as key, where
  dir_generation is non-zero and unique for unlinked but open nodes.
- Change deget() to return a vnode as it is unsafe to return a
  referenced but unlocked denode.
