mkfs.ubifs: Fix xattr nlink value
The nlink value of a xattr node must always be one, it has nothing to do with the nlink value of the inode the attribute belongs to. The bug can be observed when mounting a mkfs.ubifs generated image which contains xattrs on directories or files with hardlinks to them. When mounting such an image with chk_fs = 1 it fails with: UBIFS error (ubi0:0 pid 1833): dbg_check_filesystem: inode 3308 nlink is 3, but calculated nlink is 1 Another bug that can be triggered is an assertion in ubifs_xattr_remove() which assures that the xattr i_nlink count should be one when the xattr is removed. Fixes: 50044ef ("mkfs.ubifs: Add extended attribute support") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
