svn commit: r355913 - head/sys/fs/tmpfs

[Doug Moore]

Author: dougm

New Revision: 355913
URL: https://svnweb.freebsd.org/changeset/base/355913

Log:
  Including <sys/tmpfs.h> into non-kernel software leads to a
  compilation error because, without _KERNEL defined, the macro
  TMPFS_VALIDATE_DIR is invoked, but never defined. User-level software
  that includes sys/tmpfs.h must define _KERNEL to make the definition
  of TMPFS_VALIDATE_DIR visible.
  
  This change puts all the inline functions that, directly or
  indirectly, invoke MPASS into the scope of the _KERNEL block, allowing
  many user-space includers of <sys/tmpfs.h> to stop defining _KERNEL.
