How do you think about a wording variant like the following?

  Thus check the data structure member “sk_shutdown” (suggested by Stefano)
  after a call of the function “lock_sock” since this field is set to
  “SHUTDOWN_MASK” under the protection of “lock_sock_nested”.


Would you like to add the tag “Fixes” to the commit message?

Regards,
Markus
