+    XfsFileStoreBackend: default to disabling extsize on xfs
+    
+    This appears to be responsible for the deep scrub mismatches on some rbd
+    workloads.

+    Revert "Revert "rgw: if extra data pool name is empty, use data pool name instead""
+    
+    This reverts commit 0b6bd2545925b5e8a80d41de1fda13ffe9d30e2b.
+    
+    We confused commit 5fd8b0d1639c67e355f0fc0d7e6d7036618d87a1 with commit
+    b1a4a7cb91e164d1f8af8ce9319e3b3c1949858d in our tests.  We tested without
+    the latter, saw a failure, applied it and then reverted the former, and it
+    passed, but didn't actually resolve the problem.
+    
+    This puts them both back in place and all should be well.

+v0.80.4 Firefly
+===============
+
+This Firefly point release fixes an potential data corruption problem
+when ceph-osd daemons run on top of XFS and service Firefly librbd
+clients.  A recently added allocation hint that RBD utilizes triggers
+an XFS bug on some kernels (Linux 3.2, and likely others) that leads
+to data corruption and deep-scrub errors (and inconsistent PGs).  This
+release avoids the situation by disabling the allocation hint until we
+can validate which kernels are affected and/or are known to be safe to
+use the hint on.
+
+We recommend that all v0.80.x Firefly users urgently upgrade,
+especially if they are using RBD.
