SRU Justification: Impact: ecryptfs can cause loss of data in certain scenarios
Patch Description: cherry-picked 2.6.25.y d3e49afbb66109613c3474f2273f5830ac2dcb09. The page decrypt calls in ecryptfs_write() are both pointless and buggy. Pointless because ecryptfs_get_locked_page() has already brought the page up to date, and buggy because prior mmap writes will just be blown away by the decrypt call. This patch also removes the declaration of a now-nonexistent function ecryptfs_write_zeros().
