From d1b968dcbad59a304fafbf62b859e0692287a2f8 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 25 Aug 2017 17:30:34 +0200 Subject: btrfs-progs: drop redundant check of blocksize in read_tree_block The tree blocks are supposed to be always of nodesize. Before the parameter has been dropped, it was unlikely but possible to pass a misaligned value.
