Subject: scripts/gdb: rename pool_index to pool_index_plus_1
Date: Wed, 19 Jun 2024 15:49:11 +0800
We encounter the following issue after commit a6c1d9cb9a68 ("stackdepot:
rename pool_index to pool_index_plus_1").
(gdb) lx-dump-page-owner --pfn 262144
...
Python Exception <class 'gdb.error'>: There is no member named pool_index.
Error occurred in Python: There is no member named pool_index.
We rename pool_index to pool_index_plus_1 to fix this issue.
