Change the write path to encrypt the data only when the page is written to disk in ecryptfs_writepage. Previously, ecryptfs encrypts the page in ecryptfs_write_end which means that if there are multiple write requests to the same page, ecryptfs ends up re-encrypting that page over and over again. This patch minimizes the number of encryptions needed.

H A D | inode.c | diff 5be79de2e1ffa19d871a494697cf76cddee93384 Fri Apr 22 13:08:00 CDT 2011 Tyler Hicks <tyhicks@linux.vnet.ibm.com> eCryptfs: Flush dirty pages in setattr
After 57db4e8d73ef2b5e94a3f412108dff2576670a8a changed eCryptfs to write-back caching, eCryptfs page writeback updates the lower inode times due to the use of vfs_write() on the lower file.
To preserve inode metadata changes, such as 'cp -p' does with utimensat(), we need to flush all dirty pages early in ecryptfs_setattr() so that the user-updated lower inode metadata isn't clobbered later in writeback.
