There is the long-awaited discard support for RBD (Guangliang Zhao, Josh
Durgin), a pile of RBD bug fixes that didn't belong in late -rc's (Ilya
Dryomov, Li RongQing), a pile of fs/ceph bug fixes and performance and
debugging improvements (Yan, Zheng, John Spray), and a smattering of
cleanups (Chao Yu, Fabian Frederick, Joe Perches).

Fabian Frederick (2):
libceph: remove redundant declaration
ceph: fix bool assignments
