block: fix rq-qos breakage from skipping rq_qos_done_bio()
Details

In the Linux kernel, the following vulnerability has been resolved:

block: fix rq-qos breakage from skipping rqqosdone_bio()

a647a524a467 ("block: don't call rqqosops->donebio if the bio isn't tracked") made bioendio() skip rqqosdonebio() if BIOTRACKED is not set. While this fixed a potential oops, it also broke blk-iocost by skipping the done_bio callback for merged bios.

Before, whether a bio goes through rqqosthrottle() or rqqosmerge(), rqqosdonebio() would be called on the bio on completion with BIOTRACKED distinguishing the former from the latter. rqqosdonebio() is not called for bios which wenth through rqqos_merge(). This royally confuses blk-iocost as the merged bios never finish and are considered perpetually in-flight.

One reliably reproducible failure mode is an intermediate cgroup geting stuck active preventing its children from being activated due to the leaf-only rule, leading to loss of control. The following is from resctl-bench protection scenario which emulates isolating a web server like workload from a memory bomb run on an iocost configuration which should yield a reasonable level of protection.

# cat /sys/block/nvme2n1/device/model Samsung SSD 970 PRO 512GB # cat /sys/fs/cgroup/io.cost.model 259:0 ctrl=user model=linear rbps=834913556 rseqiops=93622 rrandiops=102913 wbps=618985353 wseqiops=72325 wrandiops=71025 # cat /sys/fs/cgroup/io.cost.qos 259:0 enable=1 ctrl=user rpct=95.00 rlat=18776 wpct=95.00 wlat=8897 min=60.00 max=100.00 # resctl-bench -m 29.6G -r out.json run protection::scenario=mem-hog,loops=1 ...

Result: isol=58.12:15.82% latimp=53.88%:143.6 workcsv=100.0% missing=3.96%

The isolation result of 58.12% is close to what this device would show without any IO control.

Fix it by introducing a new flag BIOQOSMERGED to mark merged bios and calling rqqosdonebio() on them too. For consistency and clarity, rename BIOTRACKED to BIOQOSTHROTTLED. The flag checks are moved into rqqosdone_bio() so that it's next to the code paths that set the flags.

With the patch applied, the above same benchmark shows:

# resctl-bench -m 29.6G -r out.json run protection::scenario=mem-hog,loops=1 ... Memory Hog Summary ==================
