Description
BTW: I think the .snap portion is not required for this to fail.

Problem seem to be rbd branch related, introduced by the splitting of calc_layout to helper function: plen is not updated when calling calc_layout(). This leads to rc and len not equal at ceph_readpages() which in the end leads to zeroed pages.
Fixed by commit 572b6526306fd796bfd61871dc5309b1bfa4b09f. Fix not tested yet.
