Comments are welcome ... 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. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
