Explicit timer handling is\n no longer necessary. Everything works by either queueing / modding\n / flushing / canceling the delayed_work item.\n\n* bdi_writeback_thread() becomes bdi_writeback_workfn() which runs off\n bdi_writeback-\u003edwork. On each execution, it processes\n bdi-\u003ework_list and reschedules itself if there are more things to\n do.\n\n The function also handles low-mem condition, which used to be\n handled by the forker thread. If the function is running off a\n rescuer thread, it only writes out limited number of pages so that\n the rescuer can serve other bdis too. This preserves the flusher\n creation failure behavior of the forker thread.\n\n* INIT_LIST_HEAD(\u0026bdi-\u003ebdi_list) is used to tell\n bdi_writeback_workfn() about on-going bdi unregistration so that it\n always drains work_list even if it\u0027s running off the rescuer. Note\n that the original code was broken in this regard. Under memory\n pressure, a bdi could finish unregistration with non-empty\n work_list.\n\n* The default bdi is no longer special. It now is treated the same as\n any other bdi and bdi_cap_flush_forker() is removed.\n\n* BDI_pending is no longer used. Removed.\n\n* Some tracepoints become non-applicable. The following TPs are\n removed - writeback_nothread, writeback_wake_thread,\n writeback_wake_forker_thread, writeback_thread_start,\n writeback_thread_stop.\n\nEverything, including devices coming and going away and rescuer\noperation under simulated memory pressure, seems to work fine in my\ntest setup.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Jan Kara \u003cjack@suse.cz\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Fengguang Wu \u003cfengguang.wu@intel.com\u003e\nCc: Jeff Moyer \u003cjmoyer@redhat.com\u003e\n" }, { "commit": "181387da2d64c3129e5b5186c4dd388bc5041d53", "tree": "7303c991b5c422d0c388c069b407eb648484a756", "parents": [ "229641a6f1f09e27a1f12fba38980f33f4c92975" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Mon Apr 01 19:08:06 2013 -0700" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Mon Apr 01 19:08:06 2013 -0700" }, "message": "writeback: remove unused bdi_pending_list\n\nThere\u0027s no user left.

The X11 will display either shifted image\nor otherwise distorted image on the LCD.\n\nThe problem is that the X11 tries to reconfigure the framebuffer\nand along the way calls fb_ops.fb_set_par() with X11\u0027s desired\nconfiguration values. The field of particular interest is\nfb_info-\u003evar.sync which contains non-standard values if\nconfigured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT,\nFB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform\nconfiguration. Both of these values are defined in the\ninclude/linux/mxsfb.h file.\n\nThe driver interprets these values and configures the LCD controller\naccordingly. Yet X11 only has access to the standard values for this\nfield defined in include/uapi/linux/fb.h and thus, unlike kernel,\nomits these special values. This results in distorted image on the\nLCD.\n\nThis patch moves these non-standard values into new field of the\nmxsfb_platform_data structure so the driver can in turn check this\nfield instead of the video mode field for these specific portions.\n\nMoreover, this patch prefixes these values with MXSFB_SYNC_ prefix\ninstead of FB_SYNC_ prefix to prevent confusion of subsequent users.\n\nSigned-off-by: Marek Vasut \u003cmarex@denx.de\u003e\nCc: Fabio Estevam \u003cfabio.estevam@freescale.com\u003e\nCc: Linux ARM \u003clinux-arm-kernel@lists.infradead.org\u003e\nCc: Linux FBDEV \u003clinux-fbdev@vger.kernel.org\u003e\nCc: Lothar Waßmann \u003cLW@karo-electronics.de\u003e\nCc: Sascha Hauer \u003ckernel@pengutronix.de\u003e\nTested-by: Fabio Estevam \u003cfabio.estevam@freescale.com\u003e\nSigned-off-by: Shawn Guo \u003cshawn.guo@linaro.org\u003e\n" }, { "commit": "f445f11eb2cc265dd47da5b2e864df46cd6e5a82", "tree": "f45e7180794da5bf77914e1df085e4b99d490f39", "parents": [ "6dbe51c251a327e012439c4772097a13df43c5b8" ], "author": { "name": "Kevin Hilman", "email": "khilman@linaro.org", "time": "Thu Mar 14 17:13:46 2013 -0700" }, "committer": { "name": "Marcelo Tosatti", "email": "mtosatti@redhat.com", "time": "Mon Mar 18 18:03:03 2013 -0300" }, "message": "KVM: allow host header to be included even for !CONFIG_KVM\n\nThe new context tracking subsystem unconditionally includes kvm_host.h\nheaders for the guest enter/exit macros.

This is OK for normal lock-based use because in\nthat case, the pointer cannot change. However, when the pointer is\nprotected by RCU (as in \"rcu_dereference(p)\"), then the pointer can\nchange at any time. This use case can result in the following sequence\nof events:\n\n1.\tCPU 0 invokes hlist_entry_safe(), fetches the RCU-protected\n\tpointer as sees that it is non-NULL.\n\n2.\tCPU 1 invokes hlist_del_rcu(), deleting the entry that CPU 0\n\tjust fetched a pointer to. Because this is the last entry\n\tin the list, the pointer fetched by CPU 0 is now NULL.\n\n3.\tCPU 0 refetches the pointer, obtains NULL, and then gets a\n\tNULL-pointer crash.\n\nThis commit therefore applies gcc\u0027s \"({ })\" statement expression to\ncreate a temporary variable so that the specified pointer is fetched\nonly once, avoiding the above sequence of events.

Allowing simple, safe,\nwell understood work-arounds to known problematic software.\n\nThis also addresses a rare but unfortunate problem where the filesystem\nname is not the same as it\u0027s module name and module auto-loading\nwould not work. While writing this patch I saw a handful of such\ncases. The most significant being autofs that lives in the module\nautofs4.\n\nThis is relevant to user namespaces because we can reach the request\nmodule in get_fs_type() without having any special permissions, and\npeople get uncomfortable when a user specified string (in this case\nthe filesystem type) goes all of the way to request_module.\n\nAfter having looked at this issue I don\u0027t think there is any\nparticular reason to perform any filtering or permission checks beyond\nmaking it clear in the module request that we want a filesystem\nmodule. The common pattern in the kernel is to call request_module()\nwithout regards to the users permissions. In general all a filesystem\nmodule does once loaded is call register_filesystem() and go to sleep.\nWhich means there is not much attack surface exposed by loading a\nfilesytem module unless the filesystem is mounted. In a user\nnamespace filesystems are not mounted unless .fs_flags \u003d FS_USERNS_MOUNT,\nwhich most filesystems do not set today.\n\nAcked-by: Serge Hallyn \u003cserge.hallyn@canonical.com\u003e\nAcked-by: Kees Cook \u003ckeescook@chromium.org\u003e\nReported-by: Kees Cook \u003ckeescook@google.com\u003e\nSigned-off-by: \"Eric W.
