From: Filipe Manana <redacted> Currently all the callers of btrfs_find_all_roots() pass a value of false for its ignore_offset argument. This makes the argument pointless and we can remove it and make btrfs_find_all_roots() always pass false as the ignore_offset argument for btrfs_find_all_roots_safe(). So just do that.
I thought we have some user space tool like "btrfs ins logical-resolve" needs the option for its "-o" option. Did I miss something? Or is there some recent change removed that support? Thanks, Qu
