Hi Greg et al.
A user of android-4.14 has pointed the following missing commit out.
Commit 3054426dc68e ("sched, trace: Fix prev_state output in sched_switch tracepoint") was put into linux-4.20 around rc5 to fix an issue in a tracepoint. According to the patch itself, the broken commit was 3f5fe9fef5b2 ("sched/debug: Fix task state recording/printout") which was merged at what looks like 4.15-rc2. The broken commit was also picked for 4.14.64 as 13f12749af15 ("sched/debug: Fix task state recording/printout"). The fix (3054426dc68e) was pulled into 4.19. but was not called out as needing to go back to 4.14.
Is it possible to pick 3054426dc68e ("sched, trace: Fix prev_state output in sched_switch tracepoint") for the next stable 4.14 release? If not I can do a backport for android-4.14, just let me know.
It wasn't backported because it didn't apply cleanly, since 4.4's backport of 3f5fe9fef5b2 differs from Linus's tree.
The backport for that commit was done by Sudip (Cc'ed). I'll be happy to take a backport of 3054426dc68e if someone sense one my way.
Happy to do a backport for 4.14-stable. :)
It did not apply before as the function was only renamed by: 1d48b080bcce ("sched/debug: Rename task-state printing helpers")
There was no other functionality change.
Now queued up, thanks.
