[GIT PULL] eCryptfs updates for 2.6.39-rc1

[Tyler Hicks]

Hi Linus,

The eCryptfs patches for 2.6.39-rc1 are mainly fixes. Roberto's patches
add key locking so keys aren't modified underneath us. Thieu's patch
moves encryption to writepage so userspace isn't waiting on page
encryption during each write(). My patches remove a wasteful
encrypt/write operation during file creation and fix a missing page
unlock in an error path.

The following changes since commit 40471856f2e38e9bfa8d605295e8234421110dd6:

  Merge branch 'nfs-for-2.6.39' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6 (2011-03-25 10:03:28 -0700)
