 Description   

When files are encrypted in Lustre using fscrypt, they should normally not be accessible to users without the proper encryption key. However, if a user has the encryption key loaded when they read a file, it may be decrypted in memory and saved to the PCC device in unencrypted form.
For now we should just disable PCC caching of encrypted files.
