That's all well and good, but how do we dispose of singed nodes now?

Yes, that leaves a problem here, but I'm sure that Liam can come up
with something.

Lol, this is my all-time favorite typo!


hp2:/usr/src/mm> git log | grep Singed-off-by | wc -l
59

(sounds painful)

hp2:/usr/src/linux-6.7-rc4> grep -ri singe .

Current linux-next shows:

$ git grep -iw  singe
arch/x86/events/intel/pt.c:      * In case of singe-entry ToPA, always put the self-referencing END
arch/x86/kvm/vmx/vmx.c:  * evmcs in singe VM shares same assist page.

kernel/trace/trace_events_filter.c: * struct prog_entry - a singe entry in the filter program
lib/maple_tree.c: * mas_topiary_node() - Dispose of a singe node
lib/maple_tree.c:       /* New root needs a singe node */
sound/core/seq/seq_queue.c:/* enqueue a event to singe queue */
sound/pci/rme9652/hdspm.c:      /* Changing between Singe, Double and Quad speed is not

but there is also "unsinged", "assinged", & "singel" if the -w is omitted.

And somehow the two Chinese translations of submitting-patches.rst contain
Singed-off-by.

Nodes become singed, especially around the edges, when writes are too
fast.  We have to replace them with fresh nodes, otherwise tasks can't
find the VMAs in that area.

I will have to research how these other people were able to implement
'unsinged' - maybe there's a way to reuse these singed areas more
effectively.
