+NAME
+----
+perf-kmem - Tool to trace/measure kernel memory(slab) properties
+
+SYNOPSIS
+--------
+[verse]
+'perf kmem' {record} [<options>]
+
+DESCRIPTION
+-----------
+There's two variants of perf kmem:
+
+ 'perf kmem record <command>' to record the kmem events
+ of an arbitrary workload.
+
+ 'perf kmem' to report kernel memory statistics.
+
+OPTIONS
+-------
+-i <file>::
+--input=<file>::
+ Select the input file (default: perf.data)
+
+--stat=<caller|alloc>::
+ Select per callsite or per allocation statistics
+
+-s <key[,key2...]>::
+--sort=<key[,key2...]>::
+ Sort the output (default: frag,hit,bytes)
+
+-l <num>::
+--line=<num>::
+ Print n lines only
+
+--raw-ip::
