I have a project with a submodule:X,and run

git submodule update --init --recursive

to fetch X, then made a bunch of changes on X and committed them with comment "changes YYYY", then try to push changes to master, but got something like "not in any branch"(not exact description), so I tried

git checkout origin master

Right now, X is in branch master, but git log doesn't show "changes YYYY". How can I get "changes YYYY" back?

This solves my problem:

git fsck --no-reflogs | find  "dangling commit"

    If it is a repo you have been using for a long time, you may have lots and lots of dangling commits. To locate a commit which was recently checked out (before you checked out master branch), it is probably easier to use: git reflog -10. This would show the 10 latest commits which were checked out in the current worktree. From there, you could locate the commit you were looking for and git cherry-pick <commit-hash> it to the current branch.
