Hi, In Btrfs, a hard link across subvolumes should be prohibited, but not prohibited yet. (It may be convenient if possible, I think.) If we make a hard link like this, filesystem may abort or after umount/mount, contents of file may be swapped to contents of other file(with same i-node number in same tree as 'from' file). About this, I found Christian Parpart's patch posted last year, and this patch seems to work well. http://www.spinics.net/lists/linux-btrfs/msg00749.html But this patch is not merged yet. Some work(to check more, to change error code or to simply test) shuould be done for this? -- taruisi -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
