Should it give a limit max number here when test EMLINK to handler the
filesystems which unlimited link count.
AFAIK,it use 2^31 - 1 with xfs:
/*
* 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.
