These are patterned after the\n node_to_cpumask_ptr macros.\n\n In general terms, if there is a cpumask_of_cpu_map[] then a pointer to\n the cpumask_of_cpu_map[cpu] entry is used. The cpumask_of_cpu_map\n is provided when there is a large NR_CPUS count, reducing\n greatly the amount of code generated and stack space used for\n cpumask_of_cpu(). The pointer to the cpumask_t value is needed for\n calling set_cpus_allowed_ptr() to reduce the amount of stack space\n needed to pass the cpumask_t value.\n\n If there isn\u0027t a cpumask_of_cpu_map[], then a temporary variable is\n declared and filled in with value from cpumask_of_cpu(cpu) as well as\n a pointer variable pointing to this temporary variable. Afterwards,\n the pointer is used to reference the cpumask value. The compiler\n will optimize out the extra dereference through the pointer as well\n as the stack space used for the pointer, resulting in identical code.\n\n A good example of the orthogonal usages is in net/sunrpc/svc.c:\n\n\tcase SVC_POOL_PERCPU:\n\t{\n\t\tunsigned int cpu \u003d m-\u003epool_to[pidx];\n\t\tcpumask_of_cpu_ptr(cpumask, cpu);\n\n\t\t*oldmask \u003d current-\u003ecpus_allowed;\n\t\tset_cpus_allowed_ptr(current, cpumask);\n\t\treturn 1;\n\t}\n\tcase SVC_POOL_PERNODE:\n\t{\n\t\tunsigned int node \u003d m-\u003epool_to[pidx];\n\t\tnode_to_cpumask_ptr(nodecpumask, node);\n\n\t\t*oldmask \u003d current-\u003ecpus_allowed;\n\t\tset_cpus_allowed_ptr(current, nodecpumask);\n\t\treturn 1;\n\t}\n\nSigned-off-by: Mike Travis \u003ctravis@sgi.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "961ccddd59d627b89bd3dc284b6517833bbdf25d", "tree": "4d755085845b8beeaa0bbc3d3ee66e1ccc4156a8", "parents": [ "481c5346d0981940ee63037eb53e4e37b0735c10" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Mon Jun 23 13:55:38 2008 +1000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jun 23 22:57:56 2008 +0200" }, "message": "sched: add new API sched_setscheduler_nocheck: add a flag to control access checks\n\nHidehiro Kawai noticed that sched_setscheduler() can fail in\nstop_machine: it calls sched_setscheduler() from insmod, which can\nhave CAP_SYS_MODULE without CAP_SYS_NICE.\n\nTwo cases could have failed, so are changed to sched_setscheduler_nocheck:\n kernel/softirq.c:cpu_callback()\n\t- CPU hotplug callback\n kernel/stop_machine.c:__stop_machine_run()\n\t- Called from various places, including modprobe()\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nCc: Hidehiro Kawai \u003chidehiro.kawai.ez@hitachi.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: linux-mm@kvack.org\nCc: sugita \u003cyumiko.sugita.yf@hitachi.com\u003e\nCc: Satoshi OSHIMA \u003csatoshi.oshima.fk@hitachi.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "3401a61e16a5b852d4e353c8850c857105a67a9c", "tree": "5e05731a790c48512c7fe41c5fc83b0fee6081e3", "parents": [ "4d2e7d0d77e4e1e8a21cc990c607985fdba20e66" ], "author": { "name": "Christian Borntraeger", "email": "borntraeger@de.ibm.com", "time": "Thu May 08 15:20:38 2008 +0200" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Fri May 23 13:09:34 2008 +1000" }, "message": "stop_machine: make stop_machine_run more virtualization friendly\n\nOn kvm I have seen some rare hangs in stop_machine when I used more guest\ncpus than hosts cpus. e.g. 32 guest cpus on 1 host cpu triggered the\nhang quite often.
