No, this does not look like that commit.
Why can I not just take caf6912f3f4a ("swap: fix swapfile read/write offset") directly for 5.10 and 5.11? WHat has changed to prevent that?
You're right of course, the upstream fix applies even on v5.4 so you could just take it directly for those branches if this is preferable.
But, that commit says it fixes 48d15436fde6 ("mm: remove get_swap_bio"), which is NOT what you are saying here in these patches.
So which is it? Is there a problem in 5.11 and older kernels (48d15436fde6 ("mm: remove get_swap_bio") showed up in 5.12-rc1), that requires this fix, or is there nothing needed to be backported?
As a note, I've been running swapfiles on 5.11 and earlier just fine for a very long time now, so is this really an issue?
