Unfortunately, other tracers used ftrace() to\nwrite to the buffer after they disabled it. The new disable check makes\nthese calls into a nop.\n\nThis patch changes the __ftrace that is called without the check into a\nnew api for the other tracers to use, called \"trace_function\". The other\ntracers use this interface instead when the trace CPU buffer is already\ndisabled.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "2a2cc8f7c4d0dfd75720867f7dc58d24f075edfc", "tree": "58bccce0675debd5619757a45b5aba770bf32d0e", "parents": [ "aeaee8a2c9cb4489f166ca0e39c568e8254faaa6" ], "author": { "name": "Soeren Sandmann Pedersen", "email": "sandmann@redhat.com", "time": "Mon May 12 21:20:49 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 20:55:43 2008 +0200" }, "message": "ftrace: allow the event pipe to be polled\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "aeaee8a2c9cb4489f166ca0e39c568e8254faaa6", "tree": "1b817104f60dc06c1bdd3f5e4e0bed5ee86e780e", "parents": [ "2577046740fe6d77864128c6187c11125c2449ea" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 12 21:20:49 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 20:55:33 2008 +0200" }, "message": "ftrace: build fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "2577046740fe6d77864128c6187c11125c2449ea", "tree": "1d1c691dabce954915551cd06b2b138c287256dd", "parents": [ "5e3ca0ec76fce92daa4eed0d02de9c79b1fe3920" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 12 21:20:49 2008 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri May 23 20:55:22 2008 +0200" }, "message": "ftrace: build fix\n\nno need to backmerge, only affects ftrace-enabled kernels.
