Subject: libceph: use BUG() instead of BUG_ON(1)
From: Arnd Bergmann <arnd@xxxxxxxx>
commit d24cdcd3e40a6825135498e11c20c7976b9bf545 upstream.
I ran into this compile warning, which is the result of BUG_ON(1)
not always leading to the compiler treating the code path as
unreachable:
include/linux/ceph/osdmap.h: In function 'ceph_can_shift_osds':
include/linux/ceph/osdmap.h:62:1: error: control reaches end of non-void function [-Werror=return-type]
Using BUG() here avoids the warning.
