As Shuang Qiu <[email protected]> reports: * The 32 bit link count in the inode theoretically maxes out at UINT_MAX. * Since the pathconf interface is signed, we use 2^31 - 1 instead. * The old inode format had a 16 bit link count, so its maximum is USHRT_MAX. #define XFS_MAXLINK ((1U << 31) - 1U) #define XFS_MAXLINK_1 65535U We are not able to reach such limitation.
If the mntpoint is xfs, we skip the setup for EMLINK and return TCONF in the EMLINK test.
