    fscrypt: use EEXIST when file already uses different policy · 8488cd96
    Eric Biggers authored
    As part of an effort to clean up fscrypt-related error codes, make
    FS_IOC_SET_ENCRYPTION_POLICY fail with EEXIST when the file already uses
    a different encryption policy.  This is more descriptive than EINVAL,
    which was ambiguous with some of the other error cases.
    
    I am not aware of any users who might be relying on the previous error
    code of EINVAL, which was never documented anywhere.
    
    This failure case will be exercised by an xfstest.
