The patch below does not apply to the 5.10-stable tree.

I think the reason is that "atomic_long_fetch_xyz()" got renamed to "arch_atomic_long_fetch_or()" by commit cf3ee3c8c29d ("locking/atomic: add generic arch_*() bitops") in the meantime.

Afaik, the patch should apply by literally just doing

sed 's/arch_atomic_long/atomic_long/'

on the patch before applying it.

That should fix it all the way back to the 4.19 backport.
