[linuxsh-dev] NFS issues

[NIIBE Y. <gn...@m1...>]

Here is the change.

Well, it's really difficult (for me) bug to find.

There is disagreement with maintainer of NFS wrt this change, so I
guess that this file will be here a while.

2002-03-20  NIIBE Yutaka  <gn...@m1...>

	* fs/nfs/inode.c (nfs_read_inode): Don't set inode->i_rdev here.
	(nfs_fill_inode): But set it here, instead.
	(nfs_find_actor): Reusing cached inode, clear ->i_mode.
