We fully dirty the inode to reduce some inode_lock\ncontention in several calls of __mark_inode_dirty.\n\nJan Kara: Added comment.\n\nSigned-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\nSigned-off-by: Alex Shi \u003calex.shi@intel.com\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n" }, { "commit": "2c20130f200b8f9aa746b7c7bc265ab129c29ead", "tree": "3963fb471dd62396f708912b996ff14d63565f9a", "parents": [ "1faa6ec8ccbde8c4f0237be80473a4294ebf8289", "febc88c5948f81114f64c3412011d695aecae233" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 08 11:15:51 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 08 11:15:51 2010 -0700" }, "message": "Merge branch \u0027semaphore-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027semaphore-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n semaphore: Add DEFINE_SEMAPHORE\n" }, { "commit": "1faa6ec8ccbde8c4f0237be80473a4294ebf8289", "tree": "7348fad546bbedddcb83d1282d9815e7e0fd2e15", "parents": [ "79637a41e466bbe7dfe394bac3c9d86a92fd55b1", "1389298f7d14f179c2fa4b4b343079bd56082c70" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 08 11:14:10 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 08 11:14:10 2010 -0700" }, "message": "Merge branch \u0027x86-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027x86-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n x86, mcheck: Avoid duplicate sysfs links/files for thresholding banks\n io-mapping: Fix the address space annotations\n x86: Fix the address space annotations of iomap_atomic_prot_pfn()\n x86, mm: Fix CONFIG_VMSPLIT_1G and 2G_OPT trampoline\n x86, hwmon: Fix unsafe smp_processor_id() in thermal_throttle_add_dev\n" }, { "commit": "79637a41e466bbe7dfe394bac3c9d86a92fd55b1", "tree": "0ee720d20572a3e1f901f78331b57612984f1e2e", "parents": [ "899edae615c806f78880077bd46f04d7f23ae6e6", "b3bd3de66f60df4c9a2076e2886a622458929056" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 08 11:13:42 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 08 11:13:42 2010 -0700" }, "message": "Merge branch \u0027core-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027core-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n gcc-4.6: kernel/*: Fix unused but set warnings\n mutex: Fix annotations to include it in kernel-locking docbook\n pid: make setpgid() system call use RCU read-side critical section\n MAINTAINERS: Add RCU\u0027s public git tree\n" }, { "commit": "e3e55ff5854655d8723ad8b307f02515aecc3df5", "tree": "7c30c2c00b7c8f8ce9a95d371b3ccd1408188d7f", "parents": [ "cbcc062abb16d39839b3d8d4e3d20360fc21eb58" ], "author": { "name": "Feng Tang", "email": "feng.tang@intel.com", "time": "Tue Sep 07 15:52:06 2010 +0800" }, "committer": { "name": "Grant Likely", "email": "grant.likely@secretlab.ca", "time": "Wed Sep 08 10:50:00 2010 -0600" }, "message": "spi/dw_spi: clean the cs_control code\n\ncommit 052dc7c45i \"spi/dw_spi: conditional transfer mode change\"\nintroduced cs_control code, which has a bug by using bit offset\nfor spi mode to set transfer mode in control register.

worklist or executing. This is used to implement the\nmax_active limit and workqueue freezing. If a work item is queued\nafter nr_active has already reached max_active, the work item doesn\u0027t\nincrement nr_active and is put on the delayed queue and gets activated\nlater as previous active work items retire.\n\ntry_to_grab_pending() which is used in the cancellation path\nunconditionally decremented nr_active whether the work item being\ncancelled is currently active or delayed, so cancelling a delayed work\nitem makes nr_active underflow. This breaks max_active enforcement\nand triggers BUG_ON() in destroy_workqueue() later on.\n\nThis patch fixes this bug by adding a flag WORK_STRUCT_DELAYED, which\nis set while a work item in on the delayed list and making\ntry_to_grab_pending() decrement nr_active iff the work item is\ncurrently active.\n\nThe addition of the flag enlarges cwq alignment to 256 bytes which is\ngetting a bit too large.

Then,\nacpi_pci_osc_control_set() will run _OSC queries in a loop until\nthe mask of _OSC control bits returned by the BIOS is equal to the\nmask passed to it.

The lglock provides fast access to the per-cpu lists\nto add and remove files. It also provides a snapshot of all the per-cpu lists\n(although this is very slow).\n\nOne difficulty with this approach is that a file can be removed from the list\nby another CPU. We must track which per-cpu list the file is on with a new\nvariale in the file struct (packed into a hole on 64-bit archs). Scalability\ncould suffer if files are frequently removed from different cpu\u0027s list.\n\nHowever loads with frequent removal of files imply short interval between\nadding and removing the files, and the scheduler attempts to avoid moving\nprocesses too far away. Also, even in the case of cross-CPU removal, the\nhardware has much more opportunity to parallelise cacheline transfers with N\ncachelines than with 1.\n\nA worst-case test of 1 CPU allocating files subsequently being freed by N CPUs\ndegenerates to contending on a single lock, which is no worse than before.
