ksmbd: add user namespace support For user namespace support, call vfs functions with struct user_namespace got from struct path. This patch have been tested mannually as below. Create an id-mapped mount using the mount-idmapped utility (https://github.com/brauner/mount-idmapped). $ mount-idmapped --map-mount b:1003:1002:1 /home/foo <EXPORT DIR>/foo (the user, "foo" is 1003, and the user "bar" is 1002). And mount the export directory using cifs with the user, "bar". succeed to create/delete/stat/read/write files and directory in the <EXPORT DIR>/foo. But fail with a bind mount for /home/foo.
