Al Viro 53729dbbd2 use ->d_seq to get coherency between ->d_inode and ->d_flags ...

commit a528aca7f3 upstream.

Games with ordering and barriers are way too brittle.  Just
bump ->d_seq before and after updating ->d_inode and ->d_flags
type bits, so that verifying ->d_seq would guarantee they are
coherent.
