From 1b86826d12dc4acf9576cad9c43da74025dc8074 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Wed, 17 May 2017 11:38:35 -0400 Subject: btrfs: cleanup root usage by btrfs_get_alloc_profile There are two places where we don't already know what kind of alloc profile we need before calling btrfs_get_alloc_profile, but we need access to a root everywhere we call it. This patch adds helpers for btrfs_{data,metadata,system}_alloc_profile() and relegates btrfs_system_alloc_profile to a static for use in those two cases. The next patch will eliminate one of those.
