  "message": "project: fix m/ pseudo ref handling with git worktrees\n\nSince most ref namespaces are shared among all worktrees, trying to\nset the pseudo m/\u003cbranch\u003e in the common git repo ends up clobbering\neach other when using shared checkouts.  For example, in CrOS:\n  \u003cproject path\u003d\"src/third_party/kernel/v3.8\"\n           name\u003d\"chromiumos/third_party/kernel\"\n           revision\u003d\"refs/heads/chromeos-3.8\" /\u003e\n  \u003cproject path\u003d\"src/third_party/kernel/v3.10\"\n           name\u003d\"chromiumos/third_party/kernel\"\n           revision\u003d\"refs/heads/chromeos-3.10\" /\u003e\n\nTrying to set m/master in chromiumos/third_party/kernel.git/ will\nkeep clobbering the other.\n\nInstead, when using git worktrees, lets set the m/ pseudo ref to\npoint into the refs/worktree/ namespace which is unique to each\ngit worktree.  So we have in the common dir:\n  chromiumos/third_party/kernel.git/:\n    refs/remotes/m/master:\n      ref: refs/worktree/m/master\nAnd then in each worktree we point refs/worktree/m/master to the\nrespective manifest revision expression.  Now people can use the\nm/master in each git worktree and have it resolve to the right\ncommit for that worktree.\n\nBug: https://crbug.com/gerrit/12404\nChange-Id: I78814bdd5dd67bb13218c4c6ccd64f8a15dd0a52\nReviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/256952\nTested-by: Mike Frysinger \u003cvapier@google.com\u003e\nReviewed-by: David Pursehouse \u003cdpursehouse@collab.net\u003e\n",
