Subject: RDMA/uverbs: Return not supported error code for unsupported commands
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a9ed5b38aad704bbc250f9df2e9a29ee54388829;p=linux.git

RDMA/uverbs: Return not supported error code for unsupported commands

Command that doesn't exist means that it is not supported,
so update code to return -EOPNOTSUPP in case of failure.
