      "message": "[PATCH] epoll: use unlocked wqueue operations\n\nA few days ago Arjan signaled a lockdep red flag on epoll locks, and\nprecisely between the epoll\u0027s device structure lock (-\u003elock) and the wait\nqueue head lock (-\u003elock).\n\nLike I explained in another email, and directly to Arjan, this can\u0027t happen\nin reality because of the explicit check at eventpoll.c:592, that does not\nallow to drop an epoll fd inside the same epoll fd.  Since lockdep is\nworking on per-structure locks, it will never be able to know of policies\nenforced in other parts of the code.\n\nIt was decided time ago of having the ability to drop epoll fds inside\nother epoll fds, that triggers a very trick wakeup operations (due to\npossibly reentrant callback-driven wakeups) handled by the\nep_poll_safewake() function.  While looking again at the code though, I\nnoticed that all the operations done on the epoll\u0027s main structure wait\nqueue head (-\u003ewq) are already protected by the epoll lock (-\u003elock), so that\nlocked-style functions can be used to manipulate the -\u003ewq member.  This\nmakes both a lock-acquire save, and lockdep happy.\n\nRunning totalmess on my dual opteron for a while did not reveal any problem\nso far:\n\nhttp://www.xmailserver.org/totalmess.c\n\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
