From f981fec12cc5d2c07942301744b9ea61228bf246 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 22 Nov 2021 17:04:19 -0500 Subject: [PATCH] btrfs: fail if fstrim_range->start == U64_MAX We've always been failing generic/260 because it's testing things we actually don't care about and thus won't fail for. However we probably should fail for fstrim_range->start == U64_MAX since we clearly can't trim anything past that. This in combination with an update to generic/260 will allow us to pass this test properly.
