It's up to the developer to place their interfaces in the category they
wish for it to start out in.
Notable bits of non-ABI, which should not under any circumstances be considered
stable:
- Kconfig. Userspace should not rely on the presence or absence of any
particular Kconfig symbol, in /proc/config.gz, in the copy of .config
commonly installed to /boot, or in any invocation of the kernel build
process.
- Kernel-internal symbols. Do not rely on the presence, absence, location, or

combining this information with the application's CPU allocation.
We export "total", "file", "anon" and "unevictable" pages per-node for
each memcg. The ouput format of memory.numa_stat is:
Each memcg's numa_stat file includes "total", "file", "anon" and "unevictable"
per-node page counts including "hierarchical_<counter>" which sums up all
hierarchical children's values in addition to the memcg's own value.
The ouput format of memory.numa_stat is:
total=<total pages> N0=<node 0 pages> N1=<node 1 pages> ...
file=<total file pages> N0=<node 0 pages> N1=<node 1 pages> ...
anon=<total anon pages> N0=<node 0 pages> N1=<node 1 pages> ...
unevictable=<total anon pages> N0=<node 0 pages> N1=<node 1 pages> ...
hierarchical_<counter>=<counter pages> N0=<node 0 pages> N1=<node 1 pages> ...
And we have total = file + anon + unevictable.
The "total" count is sum of file + anon + unevictable.

When kptr_restrict is set to (0), the default, there are no restrictions.
When kptr_restrict is set to (1), kernel pointers printed using the %pK
format specifier will be replaced with 0's unless the user has CAP_SYSLOG
and effective user and group ids are equal to the real ids. This is
because %pK checks are done at read() time rather than open() time, so
if permissions are elevated between the open() and the read() (e.g via
a setuid binary) then %pK will not leak kernel pointers to unprivileged
users. Note, this is a temporary solution only. The correct long-term
solution is to do the permission checks at open() time. Consider removing
world read permissions from files that use %pK, and using dmesg_restrict
to protect against uses of %pK in dmesg(8) if leaking kernel pointer
values to unprivileged users is a concern.
When kptr_restrict is set to (2), kernel pointers printed using
