From e9f9f61d0cdcb7f0b0b5feb2d84aa1c5894751f3 Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Mon, 7 Jun 2021 12:15:08 -0700 Subject: ext4: consolidate checks for resize of bigalloc into ext4_resize_begin Two different places checked for attempts to resize a filesystem with the bigalloc feature. Move the check into ext4_resize_begin, which both places already call.
