From fa104a879073f3974d673ad8c609d986042cf666 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Tue, 1 Nov 2022 16:15:49 +0000 Subject: [PATCH] btrfs: constify ulist parameter of ulist_next() The ulist_next() iterator function does not need to change the given ulist so make it const. This will allow the next patch in the series to pass a ulist to a function that does not need, and should not, modify the ulist.
