The only user of this variable is inside of an #ifdef, causing
a warning without CONFIG_INET:
net/core/filter.c: In function '____bpf_sock_ops_cb_flags_set':
net/core/filter.c:3382:6: error: unused variable 'val' [-Werror=unused-variable]
int val = argval & BPF_SOCK_OPS_ALL_CB_FLAGS;
This replaces the #ifdef with a nicer IS_ENABLED() check that
makes the code more readable and avoids the warning.
Fixes: b13d880721 ("bpf: Adds field bpf_sock_ops_cb_flags to tcp_sock")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
