From c57ed6ca6b1b0655bba4fff97ad10e32dba4a81d Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Wed, 11 Apr 2018 15:29:35 +0800 Subject: btrfs-progs: Rename OPEN_CTREE_FS_PARTIAL to OPEN_CTREE_TEMPORARY_SUPER The old flag OPEN_CTREE_FS_PARTIAL is in fact quite easy to be confused with OPEN_CTREE_PARTIAL, which allow btrfs-progs to open damaged filesystem (like corrupted extent/csum tree). However OPEN_CTREE_FS_PARTIAL, unlike its name, is just allowing btrfs-progs to open fs with temporary superblocks (which only has 6 basic trees on SINGLE meta/sys chunks). The usage of FS_PARTIAL is really confusing here. So rename OPEN_CTREE_FS_PARTIAL to OPEN_CTREE_TEMPORARY_SUPER, and add extra comment for its behavior. Also rename BTRFS_MAGIC_PARTIAL to BTRFS_MAGIC_TEMPORARY to keep the naming consistent. And with above comment, the usage of FS_PARTIAL in dump-tree is obviously incorrect, fix it.
