Ryusuke Konishi a75de1b379 eCryptfs: fix error handling in ecryptfs_init
ecryptfs_init() exits without doing any cleanup jobs if
ecryptfs_init_messaging() fails.  In that case, eCryptfs leaves
sysfs entries, leaks memory, and causes an invalid page fault.
This patch fixes the problem.

Ryusuke Konishi 202a21d691 eCryptfs: fix lookup error for special files
When ecryptfs_lookup() is called against special files, eCryptfs generates
the following errors because it tries to treat them like regular eCryptfs
files.

Error opening lower file for lower_dentry [0xffff810233a6f150], lower_mnt [0xffff810235bb4c80], and flags
[0x8000]
Error opening lower_file to read header region
Error attempting to read the [user.ecryptfs] xattr from the lower file; return value = [-95]
Valid metadata not found in header region or xattr region; treating file as unencrypted

For instance, the problem can be reproduced by the steps below.

  # mkdir /root/crypt /mnt/crypt
  # mount -t ecryptfs /root/crypt /mnt/crypt
  # mknod /mnt/crypt/c0 c 0 0
  # umount /mnt/crypt
  # mount -t ecryptfs /root/crypt /mnt/crypt
  # ls -l /mnt/crypt

This patch fixes it by adding a check similar to directories and
symlinks.

Need to initialize map_bh.b_state to zero.  Otherwise, in case of a faulty
user-buffer its possible to go into dio_zero_block() and submit a page by
mistake - since it checks for buffer_new().

Sunil Mushran 480214d71f ocfs2: Fix rename/extend race
If one process is extending a file while another is renaming it, there
exists a window when rename could flush the old inode's stale i_size to
disk. This patch recognizes the fact that rename is only updating the old
inode's ctime, so it ensures only that value is flushed to disk.

Mark Fasheh c11e9fafb3 ocfs2: Restrict inode changes in ocfs2_update_inode_atime()
ocfs2_update_inode_atime() calls ocfs2_mark_inode_dirty() to push changes
from the struct inode into the ocfs2 disk inode. The problem is,
ocfs2_mark_inode_dirty() might change other fields, depending on what
happened to the struct inode. Since we don't always have locking to
serialize changes to other fields (like i_size, etc), just fix things up to
only touch the atime field.

Trond Myklebust 45328c354e NFS: Fix NFSv4 open stateid regressions
Do not allow cached open for O_RDONLY or O_WRONLY unless the file has been
previously opened in these modes.

Also Fix the calculation of the mode in nfs4_close_prepare. We should only
issue an OPEN_DOWNGRADE if we're sure that we will still be holding the
correct open modes. This may not be the case if we've been doing delegated
opens.

Finally, there is no need to adjust the open mode bit flags in
nfs4_close_done(): that has already been done in nfs4_close_prepare().

Cyrill Gorcunov ca76d2d803 UDF: fix UID and GID mount option ignorance
This patch fix weird behaviour of UDF mounting procedure.  To get UID
changed (for now) we have to type

	mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point

and specifying two uid at once is strange a bit.  So with the patch we are
able to mount without additional 'uid=ignore' option.  The same for GID
option is done.

This patch will not break current mount scheme (with two option).

Btw this does fix (I hope) the following
