ecryptfs: remove unnecessary decrypt when extending a file Removes an unecessary page decrypt from ecryptfs_begin_write when the page is beyond the current file size. Previously, the call to ecryptfs_decrypt_page would result in a read of 0 bytes, but still attempt to decrypt an entire page. This patch detects that case and merely zeros the page before marking it up-to-date. Signed-off-by: Frank Swiderski <fes@chromium.org> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
