Yeah, we have a bit back port headache here. Got it, that resolves the field-name confusion on my side. I will rebase the test harness onto Miklos' fuse.git for-next tip (and cross-check against linux-next), then rerun the two-arm comparison against that base: revert vs apply with the abort/release race-widening kept in place, 2x50 iterations each under KASAN + lockdep + kmemleak, with full splats and reproducer attached on report-back. The stable-backport question is parked until the for-next arm lands clean. Once the trace set is in hand I will fold the v6.14 field-name delta into a separate backport note rather than mixing it into the mainline result. Assisted-by: Claude:claude-opus-4-7 berkoc-pipeline
