How does error code 131 map to ENOLCK?

[AndreRicardo-Zoetis]

In the markdown below states "0x83 in hex is 131 in decimal which is the errno value for ENOLCK."

`0x83` in hex is `131` in decimal which is the errno value for `ENOLCK`.

How does 131 map to ENOLCK? I've did some search, only saw ENOLCK being mapped to error 37.

You are right--that is incorrect. It should either be 37 (0x25)

or ENOTRECOVERABLE (invalid request code) as per https://github.com/torvalds/linux/blob/5be63fc19fcaa4c236b307420483578a56986a37/include/uapi/asm-generic/errno.h#L117

Feel free to send PR to fix the example.
