[patch] Btrfs: clean up an error code in btrfs_init_space_info()

Show all headers | View raw

If we return 1 here, then the caller treats it as an error and returns
-EINVAL.  It causes a static checker warning to treat positive returns
as an error.

I would appreciate a little review here.  This patch doesn't change
behavior, but it's possible that we had intended to do something else.
