Epoll (efd1) has installed a\n\u003e callback wakeup entry on that queue, and the wake_up() performed by the\n\u003e \"dfd\" net code will end up in ep_poll_callback(). At this point epoll\n\u003e (efd1) notices that it may have some event ready, so it needs to wake up\n\u003e the waiters on its poll wait list (efd2). So it calls ep_poll_safewake()\n\u003e that ends up in another wake_up(), after having checked about the\n\u003e recursion constraints. That are, no more than EP_MAX_POLLWAKE_NESTS, to\n\u003e avoid stack blasting. Never hit the same queue, to avoid loops like:\n\u003e\n\u003e \tepoll_ctl(efd2, EPOLL_CTL_ADD, efd1, ...);\n\u003e \tepoll_ctl(efd3, EPOLL_CTL_ADD, efd2, ...);\n\u003e \tepoll_ctl(efd4, EPOLL_CTL_ADD, efd3, ...);\n\u003e \tepoll_ctl(efd1, EPOLL_CTL_ADD, efd4, ...);\n\u003e\n\u003e The code \"if (tncur-\u003ewq \u003d\u003d wq || ...\" prevents re-entering the same\n\u003e queue/lock.\n\nSince the epoll code is very careful to not nest same instance locks\nallow the recursion.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nTested-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\nAcked-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Since we loop in a lockless fashion, we want to be\nO(nready), and we don\u0027t want to flash on/off the spinlock for every event, we\nhave the poll callback to use a secondary list to queue events while we\u0027re\ninside the event delivery loop.  The rw_semaphore has been turned into a\nmutex.  This patch also adds the wait-exclusive flag, as suggested by Davi\nArnaut.\n\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "epoll: optimizations and cleanups\n\nEpoll is doing multiple passes over the ready set at the moment, because of\nthe constraints over the f_op-\u003epoll() call.  Looking at the code again, I\nnoticed that we already hold the epoll semaphore in read, and this\n(together with other locking conditions that hold while doing an\nepoll_wait()) can lead to a smarter way [1] to \"ship\" events to userspace\n(in a single pass).\n\nThis is a stress application that can be used to test the new code.  It\nspwans multiple thread and call epoll_wait() and epoll_ctl() from many\nthreads.  Stress tested on my dual Opteron 254 w/out any problems.\n\nhttp://www.xmailserver.org/totalmess.c\n\nThis is not a benchmark, just something that tries to stress and exploit\npossible problems with the new code.\nAlso, I made a stupid micro-benchmark:\n\nhttp://www.xmailserver.org/epwbench.c\n\n[1] Considering that epoll must be thread-safe, there are five ways we can\n    be hit during an epoll_wait() transfer loop (ep_send_events()):\n\n    1) The epoll fd going away and calling ep_free\n       This just can\u0027t happen, since we did an fget() in sys_epoll_wait\n\n    2) An epoll_ctl(EPOLL_CTL_DEL)\n       This can\u0027t happen because epoll_ctl() gets ep-\u003esem in write, and\n       we\u0027re holding it in read during ep_send_events()\n\n    3) An fd stored inside the epoll fd going away\n       This can\u0027t happen because in eventpoll_release_file() we get\n       ep-\u003esem in write, and we\u0027re holding it in read during\n       ep_send_events()\n\n    4) Another epoll_wait() happening on another thread\n       They both can be inside ep_send_events() at the same time, we get\n       (splice) the ready-list under the spinlock, so each one will get\n       its own ready list. Note that an fd cannot be at the same time\n       inside more than one ready list, because ep_poll_callback() will\n       not re-queue it if it sees it already linked:\n\n       if (ep_is_linked(\u0026epi-\u003erdllink))\n                goto is_linked;\n\n       Another case that can happen, is two concurrent epoll_wait(),\n       coming in with a userspace event buffer of size, say, ten.\n       Suppose there are 50 event ready in the list. The first\n       epoll_wait() will \"steal\" the whole list, while the second, seeing\n       no events, will go to sleep. But at the end of ep_send_events() in\n       the first epoll_wait(), we will re-inject surplus ready fds, and we\n       will trigger the proper wake_up to the second epoll_wait().\n\n    5) ep_poll_callback() hitting us asyncronously\n       This is the tricky part. As I said above, the ep_is_linked() test\n       done inside ep_poll_callback(), will guarantee us that until the\n       item will result linked to a list, ep_poll_callback() will not try\n       to re-queue it again (read, write data on any of its members). When\n       we do a list_del() in ep_send_events(), the item will still satisfy\n       the ep_is_linked() test (whatever data is written in prev/next,\n       it\u0027ll never be its own pointer), so ep_poll_callback() will still\n       leave us alone. It\u0027s only after the eventual smp_mb()+INIT_LIST_HEAD(\u0026epi-\u003erdllink)\n       that it\u0027ll become visible to ep_poll_callback(), but at the point\n       we\u0027re already past it.\n\n[akpm@osdl.org: 80 cols]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

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.

      "message": "[PATCH] VFS: Permit filesystem to override root dentry on mount\n\nExtend the get_sb() filesystem operation to take an extra argument that\npermits the VFS to pass in the target vfsmount that defines the mountpoint.\n\nThe filesystem is then required to manually set the superblock and root dentry\npointers.  For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing.  In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n     pointer argument and return an integer, so most filesystems have to change\n     very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n     normally call simple_set_mnt() to instantiate the vfsmount. This will\n     always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n     dcache upon superblock destruction rather than shrink_dcache_anon().\n\n     This is required because the superblock may now have multiple trees that\n     aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n     currently called functions assume that the whole tree is rooted at s_root,\n     and that anonymous dentries are not the roots of trees which results in\n     dentries being left unculled.\n\n     However, with the way NFS superblock sharing are currently set to be\n     implemented, these assumptions are violated: the root of the filesystem is\n     simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n     inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n     with child trees.\n\n     [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n     changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This is obviously\nwrong since another thread might do a close() on that fd# before we set the\nfile-\u003eprivate_data member.
