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?
My bad, just saw the reply from David.

Then it looks completely fine to me.
