btrfs-progs: mkfs: support free space tree as -R option Add a runtime feature (-R) flag for the free space tree. A filesystem that is mkfs'd with -R free-space-tree then mounted with no options has the same contents as one mkfs'd without the option, then mounted with '-o space_cache=v2'. The only tricky thing is in exactly how to call the tree creation code. Using btrfs_create_free_space_tree as is did not quite work, because an extra reference to the eb (root->commit_root) is leaked, which mkfs complains about with a warning. I opted to follow how the uuid tree is created by adding it to the dirty roots list for cleanup by commit_tree_roots in commit_transaction. As a result, btrfs_create_free_space_tree no longer exactly matches the version in the kernel sources.

# Basic check if mkfs supports the runtime feature free-space-tree
btrfs-progs: tests: add protection against running out of test suite Executing the script inside the directories as './test.sh' is not supposed to work but could happen accidentally. With an exit after attempting to source the we can fix that. Signed-off-by: David Sterba <dsterba@suse.com>
