commit 4b183f613924ad536be2f8bd12b307e9c5a96bf6 upstream.
(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 encounter 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.
