["Juergen Hannken-Illjes" <hannken%netbsd.org@localhost>]

Module Name:    src
Committed By:   hannken
Date:           Mon Apr  4 19:16:58 UTC 2011

Modified Files:
        src/sys/fs/msdosfs: denode.h msdosfs_denode.c msdosfs_vfsops.c
        src/tests/fs/vfs: t_vfsops.c

Log Message:
Msdosfs on-disk meta data is not sufficient to create or validate file handles.

Maintain a tree of file handles, create nodes from msdosfs_vptofh() and keep
them until either the file gets unlinked or the file system gets unmounted.

Fixes the msdosfs part of PR #43745 (fhopen of an unlinked file causes problems
on multiple file systems)
