Neat.
- bdflush wakeups
- pages written via page_launder's writepage by kswapd
- pages written via page_launder's writepage by non-PF_MEMALLOC
tasks. (ext3 has an interest in this because of nasty cross-fs
reentrancy and journal overflow problems with writepage)
- shrink_icache call rate
- amount of stuff freed by shrink_icache
- ditto for shrink_dcache.
