[PATCH] ecryptfs: remove unnecessary i_version bump

[PATCH] ecryptfs: remove unnecessary i_version bump

[Jeff Layton]

From: Jeff Layton <jlayton@redhat.com>

There is no need to bump the i_version counter here, as ecryptfs does
not set the MS_I_VERSION flag, and doesn't use it internally. It also
only bumps it when the inode is instantiated, which doesn't make much
sense.

My apologies, I've been sitting on this patch for a while now. That
should be changed to the SB_I_VERSION flag. Tyler, do you mind fixing
that up before merge, or would you like me to resend?

That's no problem. Thanks for the patch! It looks good to me and I'll
take it through my tree.
