+
+This is similar to numa_maps but operates on a per-memcg basis.  This is
+useful for providing visibility into the numa locality information within
+an memcg since the pages are allowed to be allocated from any physical
+node.  One of the usecases is evaluating application performance by
+combining this information with the application's cpu allocation.
+
+We export "total", "file", "anon" and "unevictable" pages per-node for
+each memcg.  The ouput format of memory.numa_stat is:
+
+total=<total pages> N0=<node 0 pages> N1=<node 1 pages> ...

-	* cgroup creation is out-of-control
-	* cgroup name can conflict when pids are looping
-	* it is not possible to have a single process handling
-	a lot of namespaces without falling in a exponential creation time
-	* we may want to create a namespace without creating a cgroup

+	result in the symbol name with ('S') or without ('s') offsets. Where
+	this is used on a kernel without KALLSYMS - the symbol address is
+	printed instead.
+
+	The 'B' specifier results in the symbol name with offsets and should be
+	used when printing stack backtraces. The specifier takes into
+	consideration the effect of compiler optimisations which may occur
+	when tail-call's are used and marked with the noreturn GCC attribute.
+
+	On ia64, ppc64 and parisc64 architectures function pointers are
+	actually function descriptors which must first be resolved. The 'F' and
+	'f' specifiers perform this resolution and then provide the same
+	functionality as the 'S' and 's' specifiers.
+
+Kernel Pointers:
+
+	%pK	0x01234567 or 0x0123456789abcdef
+
+	For printing kernel pointers which should be hidden from unprivileged

+	Documentation/sysctl/kernel.txt for more details.
+
+Struct Resources:
+
+	%pr	[mem 0x60000000-0x6fffffff flags 0x2200] or

+		[mem 0x0000000060000000-0x000000006fffffff pref]
+
+	For printing struct resources. The 'R' and 'r' specifiers result in a

+
+MAC/FDDI addresses:
+
+	%pM	00:01:02:03:04:05
+	%pMF	00-01-02-03-04-05
+	%pm	000102030405
+
+	For printing 6-byte MAC/FDDI addresses in hex notation. The 'M' and 'm'
+	specifiers result in a printed address with ('M') or without ('m') byte
+	separators. The default byte separator is the colon (':').
+
+	Where FDDI addresses are concerned the 'F' specifier can be used after
+	the 'M' specifier to use dash ('-') separators instead of the default
+	separator.
+
+IPv4 addresses:
+
+	%pI4	1.2.3.4
+	%pi4	001.002.003.004
+	%p[Ii][hnbl]
+
+	For printing IPv4 dot-separated decimal addresses. The 'I4' and 'i4'

+
+	The additional 'c' specifier can be used with the 'I' specifier to
