description |
Please cherry pick upstream commit c96f5471ce7d ("delayacct: Account blkio completion on the correct task") into the Ubuntu 4.13 kernel. It has also been accepted into the Linux stable branch as 4.14.15. |
== SRU Justification ==
Mainline commit e33a9bba85a8 introduced a regression in v4.11-rc1. This regression
caused delayacct_blkio_end() to be called by try_to_wake_up().
However, the call was made before we have context-switched. This patch is now correct, in that
the delay accounting ends when the I/O is complete.
Commit c96f5471ce7 is in mainline as fo v4.15-rc9.
== Fix ==
commit c96f5471ce7d2aefd0dda560cc23f08ab00bc65d
Author: Josh Snyder <joshs@netflix.com>
Date: Mon Dec 18 16:15:10 2017 +0000
delayacct: Account blkio completion on the correct task
== Regression Potential ==
Low. This commit has also been cc'd to stable, so it has had additional upstream
review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
Please cherry pick upstream commit c96f5471ce7d ("delayacct: Account blkio completion on the correct task") into the Ubuntu 4.13 kernel. It has also been accepted into the Linux stable branch as 4.14.15. |
