Right, in such cases, please, make it clear against which branch this
should be applied, i.e. if this is a longstanding bug that needs to go
to perf/urgent, i.e. to the current merge window, ASAP, or if this
is for something that was introduced in the current development branch,
perf/core.
In this case it needs to go to perf/urgent, where it applies cleanly,
perf/core has extra stuff there that fuzzes a bit.
Also, since you know the cset where this bug was introduced, please
consider adding a "Fixes:" tag, commom everywhere in the kernel:
[acme@zoo linux]$ git log | grep '^[ \t]\+Fixes:' | wc -l
3805
And we use it in tools/, sometime I add it while editing changelogs,
like in this patch:
[acme@zoo linux]$ git log tools/ | grep '^[ \t]\+Fixes:' | head -5
