In dbuf_read_verify_dnode_crypt(): - We don't need original dbuf locked there. Instead take a lock on a dnode dbuf, that is actually manipulated. - Block decryption for a dnode dbuf if it is currently being written. ARC hash lock does not protect anonymous buffers, so arc_untransform() is unsafe when used on buffers being written, that may happen in case of encrypted dnode buffers, since they are not copied by dbuf_dirty()/dbuf_hold_copy(). In dbuf_read(): - If the buffer is in flight, recheck its compression/encryption status after it is cached, since it may need arc_untransform().
