but was whitelisted in 13a9d4e899
this updates the documentation to reflect this

All other options we have use `=` as separator, labels,
log configurations, graph configurations and so on.
We should be consistent and use `=` for the security
options too.

This adds the following new syscalls that are supported in libseccomp 2.3.0,
including calls added up to kernel 4.5-rc4:
mlock2 - same as mlock but with a flag
copy_file_range - copy file contents, like splice but with reflink support.
The following are not added, and mentioned in docs:
userfaultfd - userspace page fault handling, mainly designed for process migration
The following are not added, only apply to less common architectures:
switch_endian
membarrier
breakpoint
set_tls
I plan to review the other architectures, some of which can now have seccomp
enabled in the build as they are now supported.

Fixes#20818
This syscall was blocked as there was some concern that it could be
used to bypass filtering of other syscall arguments. However none of the
potential syscalls where this could be an issue (poll, nanosleep,
clock_nanosleep, futex) are blocked in the default profile anyway.

Corrected titles to use title case. Added link to default.json and some numerical detail. Changed example JSON to a portion of the actual default file, with the correct defaultAction.

Just some suggested wording to update this page to take account of User Namespaces being available as of 1.10.

Seccomp is only *compiled* in binaries built for
distros that ship with seccomp 2.2.1 or higher,
and in the static binaries.
The static binaries are not really useful for
RHEL and CentOS, because devicemapper does
not work properly with the static binaries,
so static binaries is only an option for Ubuntu
and Debian.
