  "message": "ftrace: improve documentation\n\nImpact: extend documentation with notice of using wild cards correctly\n\nWe know that we can use wild cards to set set_ftrace_filter, but there\u0027s\nproblem when using them naively such as:\n\n   echo h* \u003e /debug/tracing/set_ftrace_filter\n\nIf there are files named with \"h\" prefix in current directory,\necho \"h*\" will echo these filenames to set_ftrace_filter, not the\nintended \"h*\".\n\nFor example:\n\n  $ cat /debug/tracing/available_filter_functions |grep ^hr |wc -l\n  23\n  $ ls\n  $ touch hraa hrdd\n  $ ls\n  hraa  hrdd\n  $ echo hr* \u003e /debug/tracing/set_ftrace_filter\n  $ cat /debug/tracing/set_ftrace_filter\n\nNo output in /debug/tracing/set_ftrace_filter!\n\nIf we use \u0027\u0027 to escape wild cards, it works:\n\n  $ ls\n  hraa  hrdd\n  $ echo \"hr*\" \u003e /debug/tracing/set_ftrace_filter\n  $ cat /debug/tracing/set_ftrace_filter |wc -l\n  23\n\nThis problem can lead to unexpected result if current directory has a\nlot of files.\n\nSigned-off-by: walimis \u003cwalimisdev@gmail.com\u003e\nAcked-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
