The conversion is done using sed -i 's@memblock_virt_alloc@memblock_alloc@g' \ $(git grep -l memblock_virt_alloc)What's the reason to do this? It seems like a lot of churn even if a mechanical change.I felt that memblock_virt_alloc_ is too long for a prefix, e.g: memblock_virt_alloc_node_nopanic, memblock_virt_alloc_low_nopanic. And for consistency I've changed the memblock_virt_alloc as well.I would keep the current API unless the name is terribly misleading or it can be improved a lot. Neither seems to be the case here. So I would rather stick with the status quo.I'm ok with the memblock_virt_alloc by itself, but having 'virt' in 'memblock_virt_alloc_try_nid_nopanic' and 'memblock_virt_alloc_low_nopanic' reduces code readability in my opinion.Well, is _nopanic really really useful in the name. Do we even need/want implicit panic/nopanic semantic? The code should rather check for the return value and decide depending on the code path. I suspect removing panic/nopanic would make the API slightly lighter.I agree that panic/nopanic should be removed. But I prefer to start with equivalent replacement to make it as automated as possible and update memblock API when the dust settles a bit.Yes, I agree with that approach. But that also doesn't justify the renamingWell, the renaming is automated :)
Yes, it is. It also adds churn to the code so I tend to prefer an existing naming unless it is completely misleading or incomprehensible. Is this something to lose sleep over. Absolutely not! Does it make sense to discuss further? I do not think so. If you strongly believe that the renaming is a good thing then just do it. -- Michal Hocko SUSE Labs
