From e8920a640be5d4ebe3fee0670639a81d4ffc904c Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Tue, 27 Mar 2012 17:09:17 +0300 Subject: Btrfs: make profile_is_valid() check more strict "0" is a valid value for an on-disk chunk profile, but it is not a valid extended profile. (We have a separate bit for single chunks in extended case) Also rename it to alloc_profile_is_valid() for clarity.
