# \[PATCH 11/13\] uprobes: convert VMA flag tests to use vma\_flags\_t - From: Lorenzo Stoakes (ARM) \ - Date: 2026-11-05 21:34:58 - List: linux-trace-kernel - Page: https://ratatoskr.run/linux-trace-kernel/2026/11/17874209 - Thread: https://ratatoskr.run/linux-mm/2026/11/17874173/t.md ```text Replace use of the legacy vm_flags_t flags with vma_flags_t values in the uprobes VMA validity checks. No functional change intended.
