Subject: [PATCH v1 0/4] ipc: Remove extra1 field abuse to pass ipc namespace

These patches are made on top of branch:

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git per-namespace-ipc-sysctls-for-v5.18

After discussion, I took into account Eric Biederman's fixes. With these
changes, the hacks of passing namespace through .extra1 are not required.

With the current design of sysctl dynamic memory allocation is
necessary.

Yes, Linus, these changes are not the refactoring you were talking
about, but I plan to try to do such a refactoring in the my next
patchset.
