… MkDir or CreateFile executed simultaneously. Get parent lock before creating inode from `Goofys.MkDir` or `Goofys.CreateFile` to avoid creating a duplicate inode. Remove get lock from `Inode.Create` and `Inode.MkDir` since it lock already acquired by the caller.

We don't need to parent lock since it is already locked from caller.

We need lock here as well, since caller already has a lock.

The folder creation is moved after acquiring the parent lock. This lock needs to be atomic between creating inode and inserting into map of inodes.

This PR seems to fix multiple issues but we need a rebase to make it work with current code base. I'm not sure you're still tracking it but we probably want to try to get this PR merged as part of the next release. |
