Thus a CPU is allowed\n to reorder memory references to an object to before the reference is\n obtained. This fixes it.\n\nWhile true, it fails to show why this is a problem. I say it is not a\nproblem because if there is a race with kref_put() such that we could\nend up referencing a free\u0027d object without this memory barrier, we\nwould still have that race with the memory barrier.\n\nThe kref_put() in question could complete (and free the object) before\nthe atomic_inc() and we\u0027d still be up shit creek.\n\nThe kref_init() case is even worse, if your object is published at this\ntime you\u0027re so wrong the memory barrier won\u0027t make a difference what\nso ever. If its not published, the act of publishing should include\nthe needed barriers/locks to make sure all writes prior to the act of\npublishing are complete such that others will only observe a complete\nobject.\n\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Oliver Neukum \u003coneukum@suse.de\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "47dbd7d90ad80edb67822f327241edcab8f3f46f", "tree": "2e8880bfaf5da28b1bf2f265981e417d9afb4678", "parents": [ "4af679cd7cbb0a0d8774b5cdb34bffcaa4e86e52" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Sat Dec 10 11:43:43 2011 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Dec 13 08:41:43 2011 -0800" }, "message": "kref: Implement kref_put in terms of kref_sub\n\nLess lines of code is better.\n\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "4af679cd7cbb0a0d8774b5cdb34bffcaa4e86e52", "tree": "b97bd32f0af95d22133e98a774966ced2eee0664", "parents": [ "175cad266774d09c57a62c65baa6b4e1edafdf3a" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Tue Dec 13 10:36:20 2011 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Dec 13 08:18:25 2011 -0800" }, "message": "kref: Inline all functions\n\nThese are tiny functions, there\u0027s no point in having them out-of-line.\n\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/n/tip-8eccvi2ur2fzgi00xdjlbf5z@git.kernel.org\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "ecf7ace9a8450303a987aa8364e53860cd50e554", "tree": "bbad2c5982c3b76462cbee9e15458072bc80055d", "parents": [ "d6ea88865d3e5b0c62040531310c1f2c6a994f46" ], "author": { "name": "Thomas Hellstrom", "email": "thellstrom@vmware.com", "time": "Tue Nov 16 15:21:07 2010 +0100" }, "committer": { "name": "Dave Airlie", "email": "airlied@redhat.com", "time": "Mon Nov 22 13:25:13 2010 +1000" }, "message": "kref: Add a kref_sub function\n\nMakes it possible to optimize batched multiple unrefs.\nInitial user will be drivers/gpu/ttm which accumulates unrefs to be\nprocessed outside of atomic code.\n\nSigned-off-by: Thomas Hellstrom \u003cthellstrom@vmware.com\u003e\nSigned-off-by: Dave Airlie \u003cairlied@redhat.com\u003e\n" }, { "commit": "db1afffab0b5d9f6d31f8f4bea44c9cb3bc59351", "tree": "5ba8fd7a5018c0772d999b8c3aa945c0efb929e0", "parents": [ "dd336c554d8926c3348a2d5f2a5ef5597f6d1a06" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Tue Mar 16 15:14:51 2010 +1100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri May 21 09:37:29 2010 -0700" }, "message": "kref: remove kref_set\n\nOf the three uses of kref_set in the kernel:\n\n One really should be kref_put as the code is letting go of a\n reference,\n Two really should be kref_init because the kref is being\n initialised.\n\nThis suggests that making kref_set available encourages bad code.\nSo fix the three uses and remove kref_set completely.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nAcked-by: Mimi Zohar \u003czohar@us.ibm.com\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "932fb06b0898f5883200f1da2e00075f0d70ba9c", "tree": "b36679ed4f534513e40a3fa1c6a390c4f6257a9b", "parents": [ "108afd0491e5bc2abda08645685da69d36688cb6" ], "author": { "name": "Robert P.
