This patch preserves the following parameter values: * Foreground BFQ weight: 100 * Foreground CFQ group_idle: 0 * Foreground CFQ weight: 1000 * Background BFQ weight: 10 * Background CFQ group_idle: 0 * Background CFQ weight: 200 The foreground BFQ weight in task_profiles.json is the default BFQ weight. From https://www.kernel.org/doc/Documentation/block/bfq-iosched.txt: "weight (namely blkio.bfq.weight or io.bfq-weight): the weight of the group inside its parent. Available values: 1..10000 (default 100). The linear mapping between ioprio and weights, described at the beginning of the tunable section, is still valid, but all weights higher than IOPRIO_BE_NR*10 are mapped to ioprio 0." Bug: 213617178 Test: Booted Android in Cuttlefish and ran the following test: Test: adb -e shell cat /sys/fs/cgroup/*/*/io.bfq.weight | sort | uniq -c Test: 22 default 10 Test: 98 default 100 Change-Id: I7dfa521363a316592852fecce9192708c7a90514 Signed-off-by: Bart Van Assche <bvanassche@google.com>
