If not, they get the noop definition.\n\nIn the long term, it\u0027s better to replace the API with the generic device\nmodel API such as DECLARE_DMA_UNMAP_ADDR. We can map the API to the\ngeneric one (like dma-mapping-compat.h does). This patch also makes the\nmigration process easier. We can remove this file after the migration.\n\nIt might be simpler to add the API to include/linux/pci.h but looks it\u0027s\nalready too large.

But I agree that there is no strong reason to care\n about inlining it.\n\n As to the arch changes, there is only one thought I\u0027d add to the\n record. It was always my thinking that for an arch where\n PTRACE_SINGLESTEP does text-modifying breakpoint insertion,\n user_enable_single_step() should not be provided. That is,\n arch_has_single_step()\u003d\u003etrue means that there is an arch facility with\n \"pure\" semantics that does not have any unexpected side effects.\n Inserting a breakpoint might do very unexpected strange things in\n multi-threaded situations. Aside from that, it is a peculiar side\n effect that user_{enable,disable}_single_step() should cause COW\n de-sharing of text pages and so forth. For PTRACE_SINGLESTEP, all these\n peculiarities are the status quo ante for that arch, so having\n arch_ptrace() itself do those is one thing. But for building other\n things in the future, it is nicer to have a uniform \"pure\" semantics\n that arch-independent code can expect.\n\n OTOH, all such arch issues are really up to the arch maintainer. As\n of today, there is nothing but ptrace using user_enable_single_step() et\n al so it\u0027s a distinction without a practical difference. If/when there\n are other facilities that use user_enable_single_step() and might care,\n the affected arch\u0027s can revisit the question when someone cares about\n the quality of the arch support for said new facility.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nAcked-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b3c1e01a09d6af2dd7811a066ffcfc5171be2bed", "tree": "e59bb3618ed20fe05caba4c8cb7e292b7b2559b1", "parents": [ "7baab93f9297da3e42a8cecfbf91d5f22f415500" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed Mar 10 15:22:44 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 12 15:52:38 2010 -0800" }, "message": "ptrace: use ptrace_request() in the remaining architectures\n\nUse ptrace_request() in the three remaining architectures that didn\u0027t use it\n(m68knommu, h8300, microblaze).

This is\nmainly useful for classifiers and subsystems that hook into components\nthat are already modules. cls_cgroup and blkio-cgroup serve as the\nexample use cases for this feature.\n\nIt provides an interface cgroup_load_subsys() and cgroup_unload_subsys()\nwhich modular subsystems can use to register and depart during runtime.\nThe net_cls classifier subsystem serves as the example for a subsystem\nwhich can be converted into a module using these changes.\n\nPatch #1 sets up the subsys[] array so its contents can be dynamic as\nmodules appear and (eventually) disappear. Iterations over the array are\nmodified to handle when subsystems are absent, and the dynamic section of\nthe array is protected by cgroup_mutex.\n\nPatch #2 implements an interface for modules to load subsystems, called\ncgroup_load_subsys, similar to cgroup_init_subsys, and adds a module\npointer in struct cgroup_subsys.\n\nPatch #3 adds a mechanism for unloading modular subsystems, which includes\na more advanced rework of the rudimentary reference counting introduced in\npatch 2.\n\nPatch #4 modifies the net_cls subsystem, which already had some module\ndeclarations, to be configurable as a module, which also serves as a\nsimple proof-of-concept.\n\nPart of implementing patches 2 and 4 involved updating css pointers in\neach css_set when the module appears or leaves. In doing this, it was\ndiscovered that css_sets always remain linked to the dummy cgroup,\nregardless of whether or not any subsystems are actually bound to it\n(i.e., not mounted on an actual hierarchy). The subsystem loading and\nunloading code therefore should keep in mind the special cases where the\nadded subsystem is the only one in the dummy cgroup (and therefore all\ncss_sets need to be linked back into it) and where the removed subsys was\nthe only one in the dummy cgroup (and therefore all css_sets should be\nunlinked from it) - however, as all css_sets always stay attached to the\ndummy cgroup anyway, these cases are ignored. Any fix that addresses this\nissue should also make sure these cases are addressed in the subsystem\nloading and unloading code.\n\nThis patch:\n\nMake subsys[] able to be dynamically populated to support modular\nsubsystems\n\nThis patch reworks the way the subsys[] array is used so that subsystems\ncan register themselves after boot time, and enables the internals of\ncgroups to be able to handle when subsystems are not present or may\nappear/disappear.\n\nSigned-off-by: Ben Blum \u003cbblum@andrew.cmu.edu\u003e\nAcked-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: \"David S.
