When BFQ is used, disk IO will hang some seconds after boot. This was also reported in some public MLs [1][2]. The fix is already in mainline, but it's not available in 4.15.

== SRU Justification ==
Three patches are cherry-picked for SRU. "block, bfq: add requeue-request hook" is the fix, while the other two are cleanups and make the whole fixes clean cherry-picks. |

== SRU Justification ==
Impact:
Disk IO hangs several seconds after booting with a bionic Ubuntu kernel
Fix:
Three patches are cherry-picked for SRU. "block, bfq: add requeue-request hook" is the fix, while the other two are cleanups and make the whole fixes clean cherry-picks.
Testcase:
Boot the kernel with BFQ as IO scheduler.
Risk of Regression:
Clean cherry-picks from upstream so the risk should be fairly low. |
