(gdb) lx-mounts mount super_block devname pathname fstype options Python Exception <class 'gdb.error'>: There is no member named list. Error occurred in Python: There is no member named list.

We encoutner the above issue after commit 2eea9ce4310d ("mounts: keep list of mounts in an rbtree"). The commit move a mount from list into rbtree.

So we can instead use rbtree to iterate all mounts information.
