ecryptfs complains about "Error encrypting page" on 4.13 Artful

[Po-Hsu Lin]

This issue was spotted on my computer for work (CID 201408-15386), installed with disk encrypted

The following error message could be found in syslog

ecryptfs_encrypt_page: Error attempting to write lower page; rc = [-4]
ecryptfs_writepage: Error encrypting page (upper index [0x0000000000000000])

Found this issue because the system is crashing frequently today, but I think this is not the cause of the crash, as the error can be found on last Thursday and Friday but the system is stable.

Check through my archived syslog, this issue was first spotted on Jan. 30 19:00, 4.13.0-32 was install earlier that day in the morning.

For older log before Jan.30 (Jan.25 / 26) with 4.13.0-31, there is no such error message in the syslog.
