名称	描述
frag_show	This walks the free areas for each zone.
pagetypeinfo_showfree	Print out the free pages at each order for each migatetype
pagetypeinfo_showblockcount	Print out the number of pageblocks for each migratetype
pagetypeinfo_showmixedcount	Print out the number of pageblocks for each migratetype that contain pages* of other types. This gives an indication of how well fallbacks are being* contained by rmqueue_fallback(). It requires information from PAGE_OWNER* to determine what is going on
zoneinfo_show	Output information about zones in @pgdat. All zones are printed regardless* of whether they are populated or not: lowmem_reserve_ratio operates on the* set of all zones and userspace would not be aware of such zones if they are
