Xiubo Li 3006137ed6 ceph: stop copying to iter at EOF on sync reads ... [ Upstream commit 1065da21e5df9d843d2c5165d5d576be000142a6 ] If EOF is encountered, ceph_sync_read() return value is adjusted down according to i_size, but the "to" iter is advanced by the actual number of bytes read. Then, when retrying, the remainder of the range may be skipped incorrectly. Ensure that the "to" iter is advanced only until EOF.
