When an fdtable is being discarded after all RCU references\nto it have expired, we must either free it directly, in the standalone case,\nor free the files_struct it is contained within, in the embedded case.\n\nCurrently the free_files field controls this behavior, but we can get rid of\nit entirely, as all the necessary information is already recorded.  We can\ndistinguish embedded and standalone fdtables using max_fds, and if it is\nembedded we can divine the relevant files_struct using container_of().\n\nSigned-off-by: Vadim Lobanov \u003cvlobanov@speakeasy.net\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] fdtable: Make fdarray and fdsets equal in size\n\nCurrently, each fdtable supports three dynamically-sized arrays of data: the\nfdarray and two fdsets.  The code allows the number of fds supported by the\nfdarray (fdtable-\u003emax_fds) to differ from the number of fds supported by each\nof the fdsets (fdtable-\u003emax_fdset).\n\nIn practice, it is wasteful for these two sizes to differ: whenever we hit a\nlimit on the smaller-capacity structure, we will reallocate the entire fdtable\nand all the dynamic arrays within it, so any delta in the memory used by the\nlarger-capacity structure will never be touched at all.\n\nRather than hogging this excess, we shouldn\u0027t even allocate it in the first\nplace, and keep the capacities of the fdarray and the fdsets equal.  This\npatch removes fdtable-\u003emax_fdset.  As an added bonus, most of the supporting\ncode becomes simpler.\n\nSigned-off-by: Vadim Lobanov \u003cvlobanov@speakeasy.net\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

As a result, it also eliminates the use of\ntsk-\u003edelays_lock which was only being used (inadequately) to safeguard\naccess to tsk-\u003edelays while a task was exiting.\n\n2.

By scaling the number of listeners\nand/or the cpus they monitor, userspace can handle the statistical data\noverload more gracefully.\n\nIn this patch, each listener registers to listen to a specific set of cpus\nby specifying a cpumask.  The interest is recorded per-cpu.  When a task\nexits on a cpu, its taskstats data is unicast to each listener interested\nin that cpu.\n\nThanks to Andrew Morton for pointing out the various scalability and\ngeneral concerns of previous attempts and for suggesting this design.\n\n[akpm@osdl.org: build fix]\nSigned-off-by: Shailabh Nagar \u003cnagar@watson.ibm.com\u003e\nSigned-off-by: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Chandra Seetharaman \u003csekharan@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] task: RCU protect task-\u003eusage\n\nA big problem with rcu protected data structures that are also reference\ncounted is that you must jump through several hoops to increase the reference\ncount.  I think someone finally implemented atomic_inc_not_zero(\u0026count) to\nautomate the common case.  Unfortunately this means you must special case the\nrcu access case.\n\nWhen data structures are only visible via rcu in a manner that is not\ndetermined by the reference count on the object (i.e.  tasks are visible until\ntheir zombies are reaped) there is a much simpler technique we can employ.\nSimply delaying the decrement of the reference count until the rcu interval is\nover.\n\nWhat that means is that the proc code that looks up a task and later\nwants to sleep can now do:\n\nrcu_read_lock();\ntask \u003d find_task_by_pid(some_pid);\nif (task) {\n\tget_task_struct(task);\n}\nrcu_read_unlock();\n\nThe effect on the rest of the kernel is that put_task_struct becomes cheaper\nand immediate, and in the case where the task has been reaped it frees the\ntask immediate instead of unnecessarily waiting an until the rcu interval is\nover.\n\nCleanup of task_struct does not happen when its reference count drops to\nzero, instead cleanup happens when release_task is called.  Tasks can only\nbe looked up via rcu before release_task is called.  All rcu protected\nmembers of task_struct are freed by release_task.\n\nTherefore we can move call_rcu from put_task_struct into release_task.  And\nwe can modify release_task to not immediately release the reference count\nbut instead have it call put_task_struct from the function it gives to\ncall_rcu.\n\nThe end result:\n\n- get_task_struct is safe in an rcu context where we have just looked\n  up the task.\n\n- put_task_struct() simplifies into its old pre rcu self.\n\nThis reorganization also makes put_task_struct uncallable from modules as\nit is not exported but it does not appear to be called from any modules so\nthis should not be an issue, and is trivially fixed.\n\nSigned-off-by: Eric W.

      "message": "[PATCH] mm: update_hiwaters just in time\n\nupdate_mem_hiwater has attracted various criticisms, in particular from those\nconcerned with mm scalability.  Originally it was called whenever rss or\ntotal_vm got raised.  Then many of those callsites were replaced by a timer\ntick call from account_system_time.  Now Frank van Maarseveen reports that to\nbe found inadequate.  How about this?  Works for Frank.\n\nReplace update_mem_hiwater, a poor combination of two unrelated ops, by macros\nupdate_hiwater_rss and update_hiwater_vm.  Don\u0027t attempt to keep\nmm-\u003ehiwater_rss up to date at timer tick, nor every time we raise rss (usually\nby 1): those are hot paths.  Do the opposite, update only when about to lower\nrss (usually by many), or just before final accounting in do_exit.  Handle\nmm-\u003ehiwater_vm in the same way, though it\u0027s much less of an issue.  Demand\nthat whoever collects these hiwater statistics do the work of taking the\nmaximum with rss or total_vm.\n\nAnd there has been no collector of these hiwater statistics in the tree.  The\nnew convention needs an example, so match Frank\u0027s usage by adding a VmPeak\nline above VmSize to /proc/\u003cpid\u003e/status, and also a VmHWM line above VmRSS\n(High-Water-Mark or High-Water-Memory).\n\nThere was a particular anomaly during mremap move, that hiwater_vm might be\ncaptured too high.  A fleeting such anomaly remains, but it\u0027s quickly\ncorrected now, whereas before it would stick.\n\nWhat locking?  None: if the app is racy then these statistics will be racy,\nit\u0027s not worth any overhead to make them exact.  But whenever it suits,\nhiwater_vm is updated under exclusive mmap_sem, and hiwater_rss under\npage_table_lock (for now) or with preemption disabled (later on): without\ngoing to any trouble, minimize the time between reading current values and\nupdating, to minimize those occasions when a racing thread bumps a count up\nand back down in between.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
