------------------------------------------------------ From: Kuan-Ying Lee kuan-ying.lee@canonical.com Subject: scripts/gdb: fix lx-mounts command error Date: Tue, 23 Jul 2024 14:48:59 +0800
(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.
