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. https://bugzilla.kernel.org/show_bug.cgi?id=33372 Reported-by: Rocko <rockorequin@hotmail.com> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
