Similarly to JFFS2, UBIFS supports on-the-fly compression which makes

Although, roughly, 8 KB code is added in total, page_alloc.o increase by

520 bytes and less than half of it is in hotpath. Building the kernel with

page owner and turning it on if needed would be great option to debug

kernel memory problem.

Although enabling page owner increases kernel size by several kilobytes,

most of this code is outside page allocator and its hot path. Building

the kernel with page owner and turning it on if needed would be great

option to debug kernel memory problem.



There is one notice that is caused by implementation detail. page owner

stores information into the memory from struct page extension. This memory
