1062 * With inodes index enabled, an overlay inode nlink counts the union of upper
1064 * upper inode, the following nlink modifying operations can happen:
1070 * For the first, copy up case, the union nlink does not change, whether the
1071 * operation succeeds or fails, but the upper inode nlink may change.
1072 * Therefore, before copy up, we store the union nlink value relative to the
1073 * lower inode nlink in the index inode xattr .overlay.nlink.
1075 * For the second, upper hardlink case, the union nlink should be incremented
1076 * or decremented IFF the operation succeeds, aligned with nlink change of the
1077 * upper inode. Therefore, before link/unlink/rename, we store the union nlink
1078 * value relative to the upper inode nlink in the index inode.
1082 * upper inode where the nlink xattr can be stored before the copied up upper
1088 * On-disk format for indexed nlink:
1090 * nlink relative to the upper inode - "U[+-]NUM"
1091 * nlink relative to the lower inode - "L[+-]NUM"
