that a \"simple\" reference count can never be made\nscalable, because any time a reference is dropped, we must check whether that\nwas the last reference. To do that requires communication with all other CPUs\nthat may have taken a reference count.\n\nWe can make refcounts more scalable in a couple of ways, involving keeping\ndistributed counters, and checking for the global-zero condition less\nfrequently.\n\n- check the global sum once every interval (this will delay zero detection\n for some interval, so it\u0027s probably a showstopper for vfsmounts).\n\n- keep a local count and only taking the global sum when local reaches 0 (this\n is difficult for vfsmounts, because we can\u0027t hold preempt off for the life of\n a reference, so a counter would need to be per-thread or tied strongly to a\n particular CPU which requires more locking).\n\n- keep a local difference of increments and decrements, which allows us to sum\n the total difference and hence find the refcount when summing all CPUs. Then,\n keep a single integer \"long\" refcount for slow and long lasting references,\n and only take the global sum of local counters when the long refcount is 0.\n\nThis last scheme is what I implemented here. Attached mounts and process root\nand working directory references are \"long\" references, and everything else is\na short reference.\n\nThis allows scalable vfsmount references during path walking over mounted\nsubtrees and unattached (lazy umounted) mounts with processes still running\nin them.\n\nThis results in one fewer atomic op in the fastpath: mntget is now just a\nper-CPU inc, rather than an atomic inc; and mntput just requires a spinlock\nand non-atomic decrement in the common case. However code is otherwise bigger\nand heavier, so single threaded performance is basically a wash.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n" }, { "commit": "9d55c369bb5e695e629bc35cba2ef607755b3bee", "tree": "d97cd498a67f1f7987d4403ef90e399516a3b8c9", "parents": [ "e1bb57826381199cc79fbf44e9dfeee58fc7b339" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:50:09 2011 +1100" }, "committer": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:50:32 2011 +1100" }, "message": "fs: implement faster dentry memcmp\n\nThe standard memcmp function on a Westmere system shows up hot in\nprofiles in the `git diff` workload (both parallel and single threaded),\nand it is likely due to the costs associated with trapping into\nmicrocode, and little opportunity to improve memory access (dentry\nname is not likely to take up more than a cacheline).\n\nSo replace it with an open-coded byte comparison.

This is called rcu-walk, as opposed to the current\nalgorithm which is a refcount based walk, or ref-walk.\n\nThis results in far fewer atomic operations on every path element,\nsignificantly improving path lookup performance. It also avoids cacheline\nbouncing on common dentries, significantly improving scalability.\n\nThe overall design is like this:\n* LOOKUP_RCU is set in nd-\u003eflags, which distinguishes rcu-walk from ref-walk.\n* Take the RCU lock for the entire path walk, starting with the acquiring\n of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are\n not required for dentry persistence.\n* synchronize_rcu is called when unregistering a filesystem, so we can\n access d_ops and i_ops during rcu-walk.\n* Similarly take the vfsmount lock for the entire path walk. So now mnt\n refcounts are not required for persistence. Also we are free to perform mount\n lookups, and to assume dentry mount points and mount roots are stable up and\n down the path.\n* Have a per-dentry seqlock to protect the dentry name, parent, and inode,\n so we can load this tuple atomically, and also check whether any of its\n members have changed.\n* Dentry lookups (based on parent, candidate string tuple) recheck the parent\n sequence after the child is found in case anything changed in the parent\n during the path walk.\n* inode is also RCU protected so we can load d_inode and use the inode for\n limited things.\n* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.\n* i_op can be loaded.\n\nWhen we reach the destination dentry, we lock it, recheck lookup sequence,\nand increment its refcount and mountpoint refcount. RCU and vfsmount locks\nare dropped. This is termed \"dropping rcu-walk\". If the dentry refcount does\nnot match, we can not drop rcu-walk gracefully at the current point in the\nlokup, so instead return -ECHILD (for want of a better errno). This signals the\npath walking code to re-do the entire lookup with a ref-walk.\n\nAside from the final dentry, there are other situations that may be encounted\nwhere we cannot continue rcu-walk. In that case, we drop rcu-walk (ie. take\na reference on the last good dentry) and continue with a ref-walk. Again, if\nwe can drop rcu-walk gracefully, we return -ECHILD and do the whole lookup\nusing ref-walk. But it is very important that we can continue with ref-walk\nfor most cases, particularly to avoid the overhead of double lookups, and to\ngain the scalability advantages on common path elements (like cwd and root).\n\nThe cases where rcu-walk cannot continue are:\n* NULL dentry (ie. any uncached path element)\n* parent with d_inode-\u003ei_op-\u003epermission or ACLs\n* dentries with d_revalidate\n* Following links\n\nIn future patches, permission checks and d_revalidate become rcu-walk aware. It\nmay be possible eventually to make following links rcu-walk aware.\n\nUncached path elements will always require dropping to ref-walk mode, at the\nvery least because i_mutex needs to be grabbed, and objects allocated.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n" }, { "commit": "3c22cd5709e8143444a6d08682a87f4c57902df3", "tree": "6d245491d9103a1d77a3128ed5d1d996d3794300", "parents": [ "ff0c7d15f9787b7e8c601533c015295cc68329f8" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:49:51 2011 +1100" }, "committer": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:50:27 2011 +1100" }, "message": "kernel: optimise seqlock\n\nAdd branch annotations for seqlock read fastpath, and introduce\n__read_seqcount_begin and __read_seqcount_end functions, that can avoid the\nsmp_rmb() if used carefully.

The inode must be consulted for\n permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations.

Based on a\npatch from Linus Walliej, with the following changes:\n\n- remove RX DMA support. As PL011 doesn\u0027t give us receive timeout\n interrupts, we only get notified of received data when the RX DMA\n has completed. This rather sucks for interactive use of the TTY.\n\n- remove abuse of completions. Completions are supposed to be for\n events, not to tell what condition buffers are in. Replace it with\n a simple \u0027queued\u0027 bool.\n\n- fix locking - it is only safe to access the circular buffer with the\n port lock held.\n\n- only map the DMA buffer when required - if we\u0027re ever behind an IOMMU\n this helps keep IOMMU usage down, and also ensures that we\u0027re legal\n when we change the scatterlist entry length.\n\n- fix XON/XOFF sending - we must send XON/XOFF characters out as soon\n as possible - waiting for up to 4095 characters in the DMA buffer\n to be sent first is not acceptable.\n\n- fix XON/XOFF receive handling - we need to stop DMA when instructed\n to by the TTY layer, and restart it again when instructed to. There\n is a subtle problem here: we must not completely empty the circular\n buffer with DMA, otherwise we will not be notified of XON.\n\n- change the \u0027enable_dma\u0027 flag into a \u0027using DMA\u0027 flag, and track\n whether we can use TX DMA by whether the channel pointer is non-NULL.\n This gives us more control over whether we use DMA in the driver.\n\n- we don\u0027t need to have the TX DMA buffer continually allocated for\n each port - instead, allocate it when the port starts up, and free\n it when it\u0027s shut down. Update the \u0027using DMA\u0027 flag if we get\n the buffer, and adjust the TTY FIFO size appropriately.\n\n- if we\u0027re going to use PIO to send characters, use the existing IRQ\n based functionality rather than reimplementing it. This also ensures\n we call uart_write_wakeup() at the appropriate time, otherwise we\u0027ll\n stall.\n\n- use DMA engine helper functions for type safety.\n\n- fix init when built as a module - we can\u0027t have to initcall functions,\n so we must settle on one. This means we can eliminate the deferred\n DMA initialization.\n\n- there is no need to terminate transfers on a failed prep_slave_sg()\n call - nothing has been setup, so nothing needs to be terminated.\n This avoids a potential deadlock in the DMA engine code\n (tasklet-\u003ecallback-\u003efailed prepare-\u003eterminate-\u003etasklet_disable\n which then ends up waiting for the tasklet to finish running.)\n\n- Dan says that the submission callback should not return an error:\n | dma_submit_error() is something I should have removed after commit\n | a0587bcf \"ioat1: move descriptor allocation from submit to prep\" all\n | errors should be notified by prep failing to return a descriptor\n | handle. Negative dma_cookie_t values are only returned by the\n | dma_async_memcpy* calls which translate a prep failure into -ENOMEM.\n So remove the error handling at that point. This also solves the\n potential deadlock mentioned in the previous comment.\n\nAcked-by: Linus Walleij \u003clinus.walleij@stericsson.com\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "aef1b9cef78ae65c6501850851cc3f61f9be477b", "tree": "9769972983e84620df17c13b73f70a8341c4b125", "parents": [ "20c457b8587bee4644d998331d9e13be82e05b4c", "3c0eee3fe6a3a1c745379547c7e7c904aa64f6d5" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 05 14:22:08 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 05 14:22:10 2011 +0100" }, "message": "Merge commit \u0027v2.6.37\u0027 into perf/core\n\nMerge reason: Add the final .37 tree.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "6bf4123760a5aece6e4829ce90b70b6ffd751d65", "tree": "f7c34fba897b0a1270817c415b8c095958f59add", "parents": [ "27066fd484a32c80630136aa2b91c980f3198f9d" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Wed Jan 05 12:50:16 2011 +1100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 05 14:15:50 2011 +0100" }, "message": "sched: Change wait_for_completion_*_timeout() to return a signed long\n\nwait_for_completion_*_timeout() can return:\n\n 0: if the wait timed out\n -ve: if the wait was interrupted\n +ve: if the completion was completed.\n\nAs they currently return an \u0027unsigned long\u0027, the last two cases\nare not easily distinguished which can easily result in buggy\ncode, as is the case for the recently added\nwait_for_completion_interruptible_timeout() call in\nnet/sunrpc/cache.c\n\nSo change them both to return \u0027long\u0027.
