[RFC PATCH 4/5] fscrypt: remove user-triggerable warning messages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Several warning messages were not rate limited and were user-triggerable
from FS_IOC_SET_ENCRYPTION_POLICY.  These shouldn't really have been
there in the first place, but either way they aren't as useful now that
the error codes have been improved.  So just remove them.
