From 228e25e33325865ebe589da5366449a8ecf7d0da Mon Sep 17 00:00:00 2001 From: Illia Ostapyshyn Date: Mon, 27 Apr 2026 16:24:48 +0200 Subject: [PATCH] scripts/gdb: slab: update field names of struct kmem_cache The commit 5ba6bc27b1f9 ("slab: decouple pointer to barn from kmem_cache_node") reorganized the struct kmem_cache to factor out the per-node fields to the new struct kmem_cache_per_node_ptrs. This causes the gdb scripts for lx-slabinfo and lx-slabtrace fail as they still reference the old structure. Adjust the gdb scripts to match the current state of struct kmem_cache.
