This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed- artful'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1747769] Re: Cherry pick c96f5471ce7d for delayacct fix
SRU request submitted:
https://lists.ubuntu.com/archives/kernel-team/2018-February/090261.html
** Description changed:
+ == 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
+ Date: Mon Dec 18 16:15:10 2017 +
+
+ 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.
** Also affects: linux (Ubuntu Bionic)
Importance: Medium
Assignee: Joseph Salisbury (jsalisbury)
Status: In Progress
** Changed in: linux (Ubuntu Bionic)
