It breaks bisect. > Depends on the definition of "broken". Legacy memory mode will still work for all drivers throughout the patchset. As for new memory mode, yes, it will be "broken in the middle of the patchset", but due to the fact that there's enormous amount of code to review between fbarray changes, malloc changes, contiguous allocation changes and adding new rte_memzone API's, i favored ease of code review over bisect. I can of course reorder and roll up several different patchset and all driver updates into one giant patch, but do you really want to be the one reviewing such a patch? -- Thanks, Anatoly
