As part of an effort to clean up fscrypt-related error codes, make FS_IOC_SET_ENCRYPTION_POLICY fail with ENOTDIR when the file descriptor does not refer to a directory. 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, and in some buggy kernels did not exist at all as the S_ISDIR() check was missing. This failure case will be exercised by an xfstest. Signed-off-by: Eric Biggers <ebiggers@google.com> --- fs/crypto/policy.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
