More eCryptfs fixes

Hi Linus,

The first 2 patches are code cleanups to pave the way for the 3rd patch, which fixes a race condition around the i_size field of new eCryptfs inodes. The last 3 patches are more fs/ecryptfs/inode.c code cleanups that I couldn't resist doing after I was done fixing the race condition.

Sorry for the late pull request. The reporter of the i_size race condition was nice enough to test the fix yesterday, but I haven't had access to a computer until this afternoon.

The following changes since commit 139f37f5e14cd883eee2a8a36289f544b5390a44:

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/vapier/blackfin (2011-05-28 23:12:28 -0700)
