One needs to #include <signal.h> to get the definition of the
type (sigset_t) of the mask argument to ppoll().

The nmask argument is const. The return type in numaif.h is long.
(Well, at least <numaif.h> says nmask is const. The current kernel
does not define it as a const argument, but sys_mbind() only
passes it to get_nodes(), which does treat it as const.)

If one were to implement wrappers for [gs]et_robust_list() using the
given prototypes, one would also have to include sys/types.h to get
a definition of size_t.

files and according to <http://www.sco.com/developers/devspecs/vol1a.pdf>.

The current text reflects the general worry in the kernel about
recipients of O_PATH fds being able to hardlink the referenced
files. It turns out that it was possible to link these files
regardless of any possible security concerns.
Linux 3.11 removes the capability check in AT_EMPTY_PATH.
I expect that this functionality will be generally useful,
so let's document it better.

create_module(), delete_module(), init_module(), and
query_module() are not declared in header files, but
through an accident of history glibc provides an ABI
for them that it continues to maintain, for
compatibility reasons.
