When implementing a network namespace I need to be able\nto have multiple network devices with the same name. Currently this\nis a problem for /sys/class/net/*, /sys/devices/virtual/net/*, and\npotentially a few other directories of the form /sys/ ... /net/*.\n\nWhat this patch does is to add an additional tag field to the\nsysfs dirent structure. For directories that should show different\ncontents depending on the context such as /sys/class/net/, and\n/sys/devices/virtual/net/ this tag field is used to specify the\ncontext in which those directories should be visible. Effectively\nthis is the same as creating multiple distinct directories with\nthe same name but internally to sysfs the result is nicer.\n\nI am calling the concept of a single directory that looks like multiple\ndirectories all at the same path in the filesystem tagged directories.\n\nFor the networking namespace the set of directories whose contents I need\nto filter with tags can depend on the presence or absence of hotplug\nhardware or which modules are currently loaded. Which means I need\na simple race free way to setup those directories as tagged.\n\nTo achieve a reace free design all tagged directories are created\nand managed by sysfs itself.\n\nUsers of this interface:\n- define a type in the sysfs_tag_type enumeration.\n- call sysfs_register_ns_types with the type and it\u0027s operations\n- sysfs_exit_ns when an individual tag is no longer valid\n\n- Implement mount_ns() which returns the ns of the calling process\n so we can attach it to a sysfs superblock.\n- Implement ktype.namespace() which returns the ns of a syfs kobject.\n\nEverything else is left up to sysfs and the driver layer.\n\nFor the network namespace mount_ns and namespace() are essentially\none line functions, and look to remain that.\n\nTags are currently represented a const void * pointers as that is\nboth generic, prevides enough information for equality comparisons,\nand is trivial to create for current users, as it is just the\nexisting namespace pointer.\n\nThe work needed in sysfs is more extensive. At each directory\nor symlink creating I need to check if the directory it is being\ncreated in is a tagged directory and if so generate the appropriate\ntag to place on the sysfs_dirent. Likewise at each symlink or\ndirectory removal I need to check if the sysfs directory it is\nbeing removed from is a tagged directory and if so figure out\nwhich tag goes along with the name I am deleting.\n\nCurrently only directories which hold kobjects, and\nsymlinks are supported. There is not enough information\nin the current file attribute interfaces to give us anything\nto discriminate on which makes it useless, and there are\nno potential users which makes it an uninteresting problem\nto solve.\n\nSigned-off-by: Eric W.
