Assign a higher I/O priority to foreground I/O compared to background
I/O to improve responsiveness of the foreground app.
The command below shows that this CL has the intended effect on a device
with kernel 5.10:
$ adb shell 'cd /dev/blkio && grep -aH . blkio.prio.class background/blkio.prio.class'
blkio.prio.class:none-to-rt
background/blkio.prio.class:restrict-to-be
From a device with an Android 6.1 kernel:
$ grep -aH . blkio.prio.class background/blkio.prio.class'
blkio.prio.class:promote-to-rt
background/blkio.prio.class:restrict-to-be
