[LU-15217] disable PCC for encrypted files

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.15.0
• Affects Version/s: Lustre 2.15.0
• Severity: 3
• Assignee: Qian Yingjin
• Reporter: Sebastien Buisson

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.
