Subject[PATCH BUGFIX/IMPROVEMENTS 0/4] bfq: fix regressions on slow virtual machines
Date
Hi,
we have bumped into some BFQ latency regressions on slow virtual
machines. The patches in this series fix all these regressions, apart
from the first patch, which provides an indirect contribution, by
improving the description of the mechanisms affected by these
regressions.

Thanks,
Paolo and Davide


Davide Sapienza (2):
block, bfq: increase weight-raising duration for interactive apps
block, bfq: prevent soft_rt_next_start from being stuck at infinity

Paolo Valente (2):
block, bfq: add description of weight-raising heuristics
block, bfq: remove slow-system class
