From 2050469e384ab8c723d7962f53c200d880fe180e Mon Sep 17 00:00:00 2001 From: Kuan-Ying Lee Date: Tue, 23 Jul 2024 14:48:59 +0800 Subject: [PATCH] scripts/gdb: fix lx-mounts command error (gdb) lx-mounts mount super_block devname pathname fstype options Python Exception : 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.
