inode.c
Log Message:
Add capability of checking inode generation numbers,
if a field for it exists in the stat struct.
Bug fix for unlink/creat failure:
Changes allow re-use of an inode which is no longer in use, but
still exists in the inode cache. If the stat info for the new use
matches cached info, the inode is re-used. If not, the old inode is
marked 'zombie' and removed from the inode cache to make way for
the new inode.
