get filesystem mount point in kernel module

Question

I want to get the filesystem mount point for a file system in my kernel module, which is a stackable filesystem. Eg. if /home/ab/abc is a file and /home is mounted on a diff

Answer 1

If someone still needs to "dereference" given path to its mount point there is follow_up function which does exactly this thing :) It operates on the struct path and changes it accordingly to its .mnt entry. Maybe someone will find it handy!

Edit: I've used it in the 5.6 kernel version. I don't know if it was always available (<5.6)
