ceph: fix short sync reads from the OSD If we get a short read from the OSD because the object is small, we need to zero the remainder of the buffer. For O_DIRECT reads, the attempted range is not trimmed to i_size by the VFS, so we were actually looping indefinitely. Fix by trimming by i_size, and the unconditionally zeroing the trailing range.
