Ah, I bet it was this commit: baa23a8d4360d ("tracefs: Reset permissions on
remount if permissions are options"), which added a "iput" callback to the
dentry without calling iput, leaving stale inodes around.
This is fixed with:
0bcfd9aa4dafa ("tracefs: Clear EVENT_INODE flag in tracefs_drop_inode()")
Try adding just that patch. It will at least make it go back to what was
happening before 6.8.10 (I hope!).
