To do that it currently looks up\nsecurity.capability on EVERY write (even for non executables) to decide\nwhether to drop it or not.\n\nIn btrfs this causes an additional tree walk, hitting some per file system\nlocks and quite bad scalability. In a simple read workload on a 8S\nsystem I saw over 90% CPU time in spinlocks related to that.\n\nChris Mason tells me this is also a problem in ext4, where it hits\nthe global mbcache lock.\n\nThis patch adds a simple per inode to avoid this problem. We only\ndo the lookup once per file and then if there is no xattr cache\nthe decision. All xattr changes clear the flag.\n\nI also used the same flag to avoid the suid check, although\nthat one is pretty cheap.\n\nA file system can also set this flag when it creates the inode,\nif it has a cheap way to do so. This is done for some common file systems\nin followon patches.\n\nWith this patch a major part of the lock contention disappears\nfor btrfs. Some testing on smaller systems didn\u0027t show significant\nperformance changes, but at least it helps the larger systems\nand is generally more efficient.\n\nv2: Rename is_sgid. add file system helper.\nCc: chris.mason@oracle.com\nCc: josef@redhat.com\nCc: viro@zeniv.linux.org.uk\nCc: agruen@linbit.com\nCc: Serge E.

"message": "Intel xhci: Limit number of active endpoints to 64.\n\nThe Panther Point chipset has an xHCI host controller that has a limit to\nthe number of active endpoints it can handle. Ideally, it would signal\nthat it can\u0027t handle anymore endpoints by returning a Resource Error for\nthe Configure Endpoint command, but they don\u0027t. Instead it needs software\nto keep track of the number of active endpoints, across configure endpoint\ncommands, reset device commands, disable slot commands, and address device\ncommands.\n\nAdd a new endpoint context counter, xhci_hcd-\u003enum_active_eps, and use it\nto track the number of endpoints the xHC has active. This gets a little\ntricky, because commands to change the number of active endpoints can\nfail. This patch adds a new xHCI quirk for these Intel hosts, and the new\ncode should not have any effect on other xHCI host controllers.\n\nFail a new device allocation if we don\u0027t have room for the new default\ncontrol endpoint. Use the endpoint ring pointers to determine what\nendpoints were active before a Reset Device command or a Disable Slot\ncommand, and drop those once the command completes.\n\nFail a configure endpoint command if it would add too many new endpoints.\nWe have to be a bit over zealous here, and only count the number of new\nendpoints to be added, without subtracting the number of dropped\nendpoints. That\u0027s because a second configure endpoint command for a\ndifferent device could sneak in before we know if the first command is\ncompleted. If the first command dropped resources, the host controller\nfails the command for some reason, and we\u0027re nearing the limit of\nendpoints, we could end up oversubscribing the host.\n\nTo fix this race condition, when evaluating whether a configure endpoint\ncommand will fix in our bandwidth budget, only add the new endpoints to\nxhci-\u003enum_active_eps, and don\u0027t subtract the dropped endpoints. Ignore\nchanged endpoints (ones that are dropped and then re-added), as that\nshouldn\u0027t effect the host\u0027s endpoint resources. When the configure\nendpoint command completes, subtract off the dropped endpoints.\n\nThis may mean some configuration changes may temporarily fail, but it\u0027s\nalways better to under-subscribe than over-subscribe resources.\n\n(Originally my plan had been to push the resource allocation down into the\nring allocation functions. However, that would cause us to allocate\nunnecessary resources when endpoints were changed, because the xHCI driver\nallocates a new ring for the changed endpoint, and only deletes the old\nring once the Configure Endpoint command succeeds. A further complication\nwould have been dealing with the per-device endpoint ring cache.)\n\nSigned-off-by: Sarah Sharp \u003csarah.a.sharp@linux.intel.com\u003e\n" }, { "commit": "ad808333d8201d53075a11bc8dd83b81f3d68f0b", "tree": "40f3a11f028175f61cce14088a0f93ebd68c4b60", "parents": [ "69e848c2090aebba5698a1620604c7dccb448684" ], "author": { "name": "Sarah Sharp", "email": "sarah.a.sharp@linux.intel.com", "time": "Wed May 25 10:43:56 2011 -0700" }, "committer": { "name": "Sarah Sharp", "email": "sarah.a.sharp@linux.intel.com", "time": "Fri May 27 12:08:13 2011 -0700" }, "message": "Intel xhci: Ignore spurious successful event.\n\nThe xHCI host controller in the Panther Point chipset sometimes produces\nspurious events on the event ring.

These ports can be\nswitched from the EHCI to the xHCI host (and vice versa) by a hardware MUX\nthat is controlled by registers in the xHCI PCI configuration space. The\nUSB 3.0 SuperSpeed terminations on the xHCI ports can be controlled\nseparately from the USB 2.0 data wires.\n\nThis switchover mechanism is there to support users who do a custom\ninstall of certain non-Linux operating systems that don\u0027t have official\nUSB 3.0 support. By default, the ports are under EHCI, SuperSpeed\nterminations are off, and USB 3.0 devices will show up under the EHCI\ncontroller at reduced speeds. (This was more palatable for the marketing\nfolks than having completely dead USB 3.0 ports if no xHCI drivers are\navailable.) Users should be able to turn on xHCI by default through a\nBIOS option, but users are happiest when they don\u0027t have to change random\nBIOS settings.\n\nThis patch introduces a driver method to switchover the ports from EHCI to\nxHCI before the EHCI driver finishes PCI enumeration. We want to switch\nthe ports over before the USB core has the chance to enumerate devices\nunder EHCI, or boot from USB mass storage will fail if the boot device\nconnects under EHCI first, and then gets disconnected when the port\nswitches over to xHCI.\n\nAdd code to the xHCI PCI quirk to switch the ports from EHCI to xHCI. The\nPCI quirks code will run before any other PCI probe function is called, so\nthis avoids the issue with boot devices.\n\nAnother issue is with BIOS behavior during system resume from hibernate.\nIf the BIOS doesn\u0027t support xHCI, it may switch the devices under EHCI to\nallow use of the USB keyboard, mice, and mass storage devices. It\u0027s\nsupposed to remember the value of the port routing registers and switch\nthem back when the OS attempts to take control of the xHCI host controller,\nbut we all know not to trust BIOS writers.\n\nMake both the xHCI driver and the EHCI driver attempt to switchover the\nports in their PCI resume functions. We can\u0027t guarantee which PCI device\nwill be resumed first, so this avoids any race conditions. Writing a \u00271\u0027\nto an already set port switchover bit or a \u00270\u0027 to a cleared port switchover\nbit should have no effect.\n\nThe xHCI PCI configuration registers will be documented in the EDS-level\nchipset spec, which is not public yet. I have permission from legal and\nthe Intel chipset group to release this patch early to allow good Linux\nsupport at product launch. I\u0027ve tried to document the registers as much\nas possible, so please let me know if anything is unclear.\n\nSigned-off-by: Sarah Sharp \u003csarah.a.sharp@linux.intel.com\u003e\n" }, { "commit": "e4a338d05df93ab1ebf291aca1e753064319d301", "tree": "39a843944ca23ef9a927030de7295146e8bd5dc4", "parents": [ "5f6f55809758e106eca72c6e01402c8080a88ee8" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 13:42:16 2011 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 16:02:29 2011 -0300" }, "message": "perf top: Don\u0027t stop if no kernel symtab is found\n\nWe now just warn the user about the fact and go on providing just\nuserspace samples.\n\nThis fixes a problem when no vmlinux is explicetely passed by the user,\nthus symbol_conf.vmlinux_name is NULL, no suitable vmlinux is found, and\nthen we get:\n\n aldebaran:~\u003e perf top -p 7557\n [kernel.kallsyms] with build id 44d9a989eabbd79e486bc079d6b743d397c204e0\n not found, continuing without symbols\n The (null) file can\u0027t be used\n\nReported-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLink: http://lkml.kernel.org/n/tip-cj2g81hn64wv2bipmqk4fy2m@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "5f6f55809758e106eca72c6e01402c8080a88ee8", "tree": "23a21a57154fc589d4606a6ef1856cc1b38d93e2", "parents": [ "59fb1ee95e74e8e0777289c44300cbe812aca836" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 11:53:28 2011 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 16:02:25 2011 -0300" }, "message": "perf top: Handle kptr_restrict\n\nReported-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLink: http://lkml.kernel.org/n/tip-cyl5zmi1nu35vyu7l5im2pyv@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "59fb1ee95e74e8e0777289c44300cbe812aca836", "tree": "67204d7bc49c0827947310f58419c0267d0bde87", "parents": [ "4af4c9550ccaaf0b53013ff730bc15068ffe6abc" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 11:14:00 2011 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 16:02:20 2011 -0300" }, "message": "perf top: Remove unused macro\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nCc: Tom Zanussi \u003ctzanussi@gmail.com\u003e\nLink: http://lkml.kernel.org/n/tip-weqbs0tkk2u0qp1xxdxxosfg@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "4af4c9550ccaaf0b53013ff730bc15068ffe6abc", "tree": "52d819119adb048298b35bb67e5c2cdf5cbff3d9", "parents": [ "646aaea615704010b5fd2c8c8891ff1a3a4b4f1a" ], "author": { "name": "David Ahern", "email": "dsahern@gmail.com", "time": "Fri May 27 09:58:34 2011 -0600" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri May 27 16:02:12 2011 -0300" }, "message": "perf events: initialize fd array to -1 instead of 0\n\nperf_evsel__alloc_fd allocates an array of file descriptors with the\nmemory initialized to 0.
