when set the flag of '--localize-reads', maybe peer_pg will complete read task, but peer_pg will not count read_num. the count will be modify when the Primary_pg writing

- Project changed from Ceph to RADOS
- Subject changed from pg stats count error when the fuse flag '--localize-reads' was setted to localize-reads does not increment pg stats read count
- Category deleted (
OSD)
Yeah, localize_reads has some issues. This is the least of them and would be hard to fix in the current architecture since non-primary OSDs don't have any write ability.
