Subject: sysctl: create sys/fs/binfmt_misc as an ordinary sysctl entry
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
binfmt_misc has a mount point in the middle of the sysctl and that mount point
is created as a proc_generic directory.
Doing it that way gets in the way of cleaning up the sysctl proc support as it
continues the existence of a horrible hack. So instead simply create the
directory as an ordinary sysctl directory. At least that removes the magic
special case.
