This is mostly whack-a-mole stuff - a bunch of places are passing struct path pointers around, without bothering to mark them const, even though they are not going to try and modify the contents of struct path. It's a bad practice, since there are invariants along the lines of "file->f_path stays unchanged open-to-release" and verifying those can get very unpleasant when you are forced to take detours down the long call chains that could've been avoided. Patches in that pile are independent from each other and if anyone wants to grab some of them into subsystem's tree - just say so; I'll be happy to exclude those from the vfs.git branch if they go into another tree. Currently they are in vfs.git#work.path; individual patches in followups.
