From bb55f6260b4756ba0ce46fc373f6f2e1893f752d Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Mon, 5 Aug 2019 17:47:05 +0300 Subject: [PATCH] btrfs: simplify extent type checks in run_delalloc_nocow There is no point in checking the type of the extent again just to set the 'type' variable, when this check has already been performed before. Instead, extend the original if branch with an 'else' clause. This allows to remove one local variable and make it obvious how the code flow differs for prealloc/regular extents.
