From c82f823c9b006c31059341af41da9f8b2e3e64d9 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 9 Aug 2019 17:48:21 +0200 Subject: btrfs: tie extent buffer and it's token together Further simplifaction of the get/set helpers is possible when the token is uniquely tied to an extent buffer. A condition and an assignment can be avoided. The initializations are moved closer to the first use when the extent buffer is valid. There's one exception in __push_leaf_left where the token is reused.
