If we get a keyed wakeup for a aio poll waitqueue and wake can acquire the
ctx_lock without spinning we can just complete the iocb straight from the

Hello Alexey,
AFAICT, this looks right. It seems that *most* of the machine

why you didn't sent a series patch to fix them all at once?

The early_param() is only called during kernel initialization, So Linux
marks the functions of it with __init macro to save memory.
But it forgot to mark parse_mem_block_size(). So, Make it __init as well.
Aslo mark mem_block_size variable __initdata.

That's a bad tool then, as this is used, and the build breaks when this

'msize' is often a power of two, or at least page-aligned, so avoiding
an overhead of two dozen bytes for each allocation will help the
allocator do its work and reduce memory fragmentation.

Having a specific cache for the fcall allocations helps speed up
allocations a bit, especially in case of non-"round" msizes.
The caches will automatically be merged if there are multiple caches
of items with the same size so we do not need to try to share a cache
