From e346fb6d774abf1d9a87d39b1e3eef0b7397d154 Mon Sep 17 00:00:00 2001 From: Wedson Almeida Filho Date: Sat, 30 Sep 2023 02:00:05 -0300 Subject: xattr: make the xattr array itself const As it is currently declared, the xattr_handler structs are const but the array containing their pointers is not. This patch makes it so that fs modules can place them in .rodata, which makes it harder for accidental/malicious modifications at runtime.
