Hopefully this is sufficiently paranoid, tested with PATH_MAX length symlinks, existing files, insufficient permissions, dangling symlinks. I think I got the coding style correct this time, I'll fix and resend if not.
Includes a trivial fix from my metadata patch, the documentation got lost in the merge. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
