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 block/bfq-iosched.c | 252 ++++++++++++++++++++++------------------------------ block/bfq-iosched.h | 14 +-- 2 files changed, 109 insertions(+), 157 deletions(-) -- 2.16.1
