    ns: Wire up the setns system call · 7b21fddd
    Eric W. Biederman authored
    32bit and 64bit on x86 are tested and working.  The rest I have looked
    at closely and I can't find any problems.
    setns is an easy system call to wire up.  It just takes two ints so I
    don't expect any weird architecture porting problems.
    While doing this I have noticed that we have some architectures that are
    very slow to get new system calls.  cris seems to be the slowest where
    the last system calls wired up were preadv and pwritev.  avr32 is weird
    in that recvmmsg was wired up but never declared in unistd.h.  frv is
    behind with perf_event_open being the last syscall wired up.  On h8300
    the last system call wired up was epoll_wait.  On m32r the last system
    call wired up was fallocate.  mn10300 has recvmmsg as the last system
    call wired up.  The rest seem to at least have syncfs wired up which was
    new in the 2.6.39.
    v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
    v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
    v4: Moved wiring up of the system call to another patch
    v5: ported to v2.6.39-rc6
    v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
    v7: ported to Linus's latest post 2.6.39 tree.

    Oh - ia64 wiring looks good.
