This fixes it by checking sk->sk_shutdown(suggested by Stefano) after lock_sock since sk->sk_shutdown is set to SHUTDOWN_MASK under the protection of lock_sock_nested.
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”.
Okay, will update the commit msg.
Would you like to add the tag “Fixes” to the commit message?
Sure.
Thanks
