Jeff Layton 02e37571f9 ceph: handle zero-length feature mask in session messages ... Most session messages contain a feature mask, but the MDS will routinely send a REJECT message with one that is zero-length. Commit 0fa8263367 ("ceph: fix endianness bug when handling MDS session feature bits") fixed the decoding of the feature mask, but failed to account for the MDS sending a zero-length feature mask. This causes REJECT message decoding to fail. Skip trying to decode a feature mask if the word count is zero.
