From 97355420b50aee599bcf4059b6d868a23d22f751 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 23 Aug 2021 17:30:39 -0700 Subject: xfs: make the start pointer passed to btree alloc_block functions const The @start pointer passed to each per-AG btree type's ->alloc_block function isn't supposed to be modified, since it's a hint about the location of the btree block being split that is to be fed to the allocator, so mark the parameter const.
