Description Holger Hoffstätte 2024-08-05 20:33:32 UTC

While fixing #937402 I discovered that perf does not actually apply any incremental patches on top of the base kernel tree. This is because the list of directories passed to filterdiff does not contain correct expressions (directories need a trailing /*) and therefore the applied patch file is empty.
Also filterdiff does not handle xz-compressed input, so it fails successfully with exit code 0 even before not filtering patches.


Reproducible: Always

Steps to Reproduce:
1. bump perf to e.g. 6.10.3
2. inspect patch in $WORKDIR
3. it's empty
Actual Results:  
No patch applied

Expected Results:  
Patch applied
