-// The PSI / pressure interface is described at
-//   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/accounting/psi.txt
-// Each resource (cpu, io, memory, ...) is exposed as a single file.
-// Each file may contain up to two lines, one for "some" pressure and one for "full" pressure.
-// Each line contains several averages (over n seconds) and a total in µs.
-//
-// Example io pressure file:
-// > some avg10=0.06 avg60=0.21 avg300=0.99 total=8537362
-// > full avg10=0.00 avg60=0.13 avg300=0.96 total=8183134
