Hi Greg,

Can you please revert this commit in 4.14?

seccomp: add a selftest for get_metadata

[ Upstream commit d057dc4e35e16050befa3dda943876dab39cbf80 ]

Let's test that we get the flags correctly, and that we preserve
the filter
index across the ptrace(PTRACE_SECCOMP_GET_METADATA) correctly.

PTRACE_SECCOMP_GET_METADATA was only added in 4.16
(26500475ac1b499d8636ff281311d633909f5d20)

And it's also breaking seccomp_bpf.c compilation for me:

seccomp_bpf.c: In function ‘get_metadata’:
seccomp_bpf.c:2878:26: error: storage size of ‘md’ isn’t known
struct seccomp_metadata md;
^~
