116 * (upper fsid is 0). The lowest xinobit is reserved for mapping
202 * upper files, so we cannot use the lower origin st_ino
212 * upper hardlink is not broken and that a redirected
239 * no origin on upper, we can end up here.
266 * Return the overlay inode nlinks for indexed upper inodes.
267 * Overlay inode nlink counts the union of the upper hardlinks
268 * and non-covered lower hardlinks. It does not include the upper
557 * upper fs:
619 * To avoid ino collision with legitimate xino values from upper
684 * With inodes index enabled, an overlay inode nlink counts the union of upper
686 * upper inode, the following nlink modifying operations can happen:
693 * operation succeeds or fails, but the upper inode nlink may change.
697 * For the second, upper hardlink case, the union nlink should be incremented
699 * upper inode. Therefore, before link/unlink/rename, we store the union nlink
700 * value relative to the upper inode nlink in the index inode.
704 * upper inode where the nlink xattr can be stored before the copied up upper
712 * nlink relative to the upper inode - "U[+-]NUM"
811 * checks, so NULL lower/upper in dentry must match NULL lower/upper in
813 * 'unknown' lower/upper.
