Top 3 entries: 89361 times: Page allocated via order 0, mask 0x280d2 [0xc0159f31] __handle_mm_fault+1809 [0xc011318a] do_page_fault+314 [0xc04111c4] error_code+116 Can be anything. But if I understand anything, this memory is used because someone has requested a page that is swapped out. So the memory must be used, but not reflected in meminfo, and not by a process? 35560 times: Page allocated via order 0, mask 0x201d2 [0xc0152ec2] __do_page_cache_readahead+450 [0xc015309a] do_page_cache_readahead+74 [0xc014d7b5] filemap_nopage+325 [0xc0159919] __handle_mm_fault+249 [0xc011318a] do_page_fault+314 [0xc04111c4] error_code+116 - is reflected in cache usage statistics, I guess.. 6185 times: Page allocated via order 0, mask 0x200d2 [0xc014e069] generic_file_buffered_write+329 [0xc014e814] __generic_file_aio_write_nolock+612 [0xc014eb85] generic_file_aio_write+85 [0xc01b26ff] ext3_file_write+63 [0xc016b23c] do_sync_write+204 [0xc016b9a7] vfs_write+167 [0xc016c2a7] sys_write+71 [0xc010303a] sysenter_past_esp+95 - negligible, really.. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
