No LTO (there is no GCC LTO yet afaik too),
and I guess just building debug kernel eats tons of memory

BTW GCC LTO has been maintained out of tree for a long time, but still no mainline support....

Since when has kernel compilation required this much RAM? My laptop with 16GiB of RAM uses tens of GBs of swap space during linkage step

@vbabka @larsmb threads are inherently toxic to brain as you need to take care about concurrency

why not call it just slab instead when we have only single implenentation ;)

and yeah there someone might suggest new implementation in the future but it should replace existing one to be merged... or we will have tens of allocators again (and run out of letters)

Wow, 10 years.

I always hope to accumulate sufficient experience as an engineer but also don't want to get older... but can't have both :(

congrats anyway!!
