[RFC PATCH v4 1/3] vsock/vmci: convert VMCI error code to -ENOMEM on receive

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This adds conversion of VMCI specific error code to general -ENOMEM. It
is preparation for the next patch, which changes af_vsock.c behaviour
on receive to pass value returned from transport to the user.
