To avoid name collisions, private tags should 10 # have names which begin with the developer's NetBSD login name 11 # followed by a - or _ character (e.g., thorpej_scsipi, 12 # thorpej-signal) 13 # 14 # Any branch or version tag not listed here should be assumed to be 15 # private to the developer who created it. It is inappropriate for 16 # anyone other than that developer to commit, move tags, or otherwise 17 # modify the contents of the branch. 18 # 19 # Please update this file when a new branch is ready for consumption 20 # by folks other than the maintainer, or when the use or status of an 21 # existing branch changes significantly. 22 # 23 # Format: 24 # Branch: name of branch 25 # Description: Purpose and intention of the branch 26 # Status: Active/Terminated/Dormant 27 # Start Date: date first instantiated 28 # End Date: date it was Terminated/made_Dormant, if any 29 # Base Tag: netbsd-1-5-base, etc. 30 # Maintainer: Somebody to blame. 31 # Scope: Portion of the tree covered. 32 # Notes: Various other info, perhaps explanation of special tags, 33 # who-may-commit policies, etc. 34 35 36 # Release branches: 37 38 Branch: comdex-fall-1999 39 Description: Special release branch for pre-1.5 release at 40 Fall 1999 COMDEX. 41 Status: Terminated 42 Start Date: 43 End Date: 44 Base Tag: comdex-fall-1999-base 45 Maintainer: ? 46 Scope: Entire tree. 47 Notes: 48 49 Branch: netbsd-0-9 50 Description: The NetBSD 0.9 release branch 51 Status: Terminated 52 Start Date: 53 End Date: 54 Base Tag: netbsd-0-9-base 55 Maintainer: Release Engineering <releng (a] NetBSD.org> 56 Scope: Entire tree. 57 Notes: Subsidiary tags of: netbsd-0-9-ALPHA, netbsd-0-9-ALPHA2, 58 netbsd-0-9-BETA, netbsd-0-9-RELEASE. 59 Commits restricted to release engineering. 60 61 Branch: netbsd-1-0 62 Description: The NetBSD 1.0 release branch 63 Status: Terminated 64 Start Date: 65 End Date: 66 Base Tag: netbsd-1-0-base 67 Maintainer: Release Engineering <releng (a] NetBSD.org> 68 Scope: Entire tree. 69 Notes: 70 Commits restricted to release engineering. 71 72 Branch: netbsd-1-1 73 Description: The NetBSD 1.1 release branch 74 Status: Terminated 75 Start Date: 76 End Date: 77 Base Tag: netbsd-1-1-base 78 Maintainer: Release Engineering <releng (a] NetBSD.org> 79 Scope: Entire tree. 80 Notes: 81 Commits restricted to release engineering. 82 83 Branch: netbsd-1-2 84 Description: The NetBSD 1.2 release branch 85 Status: Terminated 86 Start Date: 87 End Date: 88 Base Tag: netbsd-1-2-base 89 Maintainer: Release Engineering <releng (a] NetBSD.org> 90 Scope: Entire tree. 91 Notes: 92 Commits restricted to release engineering. 93 94 Branch: netbsd-1-3 95 Description: The NetBSD 1.3 release branch 96 Status: Terminated 97 Start Date: 98 End Date: 99 Base Tag: netbsd-1-3-base 100 Maintainer: Release Engineering <releng (a] NetBSD.org> 101 Scope: Entire tree. 102 Notes: 103 Commits restricted to release engineering. 104 105 Branch: netbsd-1-4 106 Description: The NetBSD 1.4 release branch 107 Status: Terminated 108 Start Date: 1 Apr 2000 109 End Date: 110 Base Tag: netbsd-1-4-base 111 Maintainer: 1.4 Release Engineering <releng-1-4 (a] NetBSD.org> 112 Scope: Entire tree. 113 Notes: 114 Commits restricted to release engineering. 115 116 Branch: netbsd-1-5 117 Description: The NetBSD 1.5 release branch 118 Status: Active 119 Start Date: 20 Jun 2000 120 End Date: 121 Base Tag: netbsd-1-5-base 122 Maintainer: 1.5 Release Engineering <releng-1-5 (a] NetBSD.org> 123 Scope: Entire tree. 124 Notes: 125 Commits restricted to release engineering. 126 127 Branch: netbsd-1-6 128 Description: The NetBSD 1.6 release branch 129 Status: Active 130 Start Date: 22 May 2002 131 End Date: 132 Base Tag: netbsd-1-6-base 133 Maintainer: 1.6 Release Engineering <releng-1-6 (a] NetBSD.org> 134 Scope: Entire tree. 135 Notes: 136 Commits restricted to Release Engineering. 137 138 Branch: netbsd-2-0 139 Description: The NetBSD 2.0 release branch 140 Status: Active 141 Start Date: 28 Mar 2004 142 End Date: 143 Base Tag: netbsd-2-0-base 144 Maintainer: 2.0 Release Engineering <releng-2-0 (a] NetBSD.org> 145 Scope: Entire tree.

In terms of UBC, the primary cache for 597 file data is the VM cache, which needs to operate 598 in terms of VM pages. As no existing device has native 599 pages the same size as our VM pages, there already is 600 a mapping going on between the VM system and the 601 underlying blocks. So it would be easier and cleaner 602 to adjust that to deal w/ different block sizes. 603 Also with UBC, all i/o is in terms of bytes at an offset 604 with a certain length, so the exact block size isn't a big 605 deal. 606 607 Any other wrstuden-devbsize tag may (and should) go away. 608 609 610 Branch: rtr-xorg-branch 611 Description: xorg & static build alterations to src/x11 612 Status: Active 613 Start Date: Nov 15 2004 614 End Date: 615 Base tag: rtr-xorg-branch-base 616 Maintainer: Tyler R.
