Amir Goldstein	8a2d6ed9fc	overlay: consider index dir with whiteouts clean ... Several tests check that index dir is empty after upper entries have been unlinked. With nfs_export=on, index will contain a whiteout index entry in that case so, allow chardevs when checking for clean index dir.

Amir Goldstein	29e399dae8	overlay: enable the index feature for overlay/hardlink tests ... Overlayfs hardlink test are expected to fail if overlayfs does not support the inodes index feature, so don't un them if kernel does not support the feature. If the feature is supported, enable it with the index=on mount option for the hardlink tests, regardless of the build time default determined by kernel config option CONFIG_OVERLAY_FS_INDEX.

Amir Goldstein	af55e91fd2	overlay: test nlink accounting of overlay hardlinks ... nlink of overlay inode should account for the union of lower and upper hardlinks. persistent overlay union nlink is stored in an extended attribute on the upper inode. In order to test persistent overlay nlink accounting, the test is repeated with both warm and cold dentry/inode cache.
