Prefetching appears to have a slightly negative effect on boot time, and actually makes boot time much worse when the available dm-bufio cache shrinks. Since we anticipate the dm-bufio cache will shrink (because of an increasing number of APEX dm-verity targets), disable prefetching completely. Boot time w/o this change: 12.085 Boot time with this change: 11.958 Boot time w/o this change with 128kB dm-bufio cache: 22.82 Boot time with this change with 128kB dm-bufio cache: 12.007 Test: atest google/perf/boottime/boottime-test Bug: 136247322 Change-Id: I12e342c5692fa89855d9c217f2e94287ff5642a6 |
