[PATCH] include/linux/freezer.h needs PF_FREEZE and PF_FROZEN declarations

[Cal Peake <cp@absolutedigital.net>]

JFS (modular, if it matters) fails to build with this error:

  In file included from fs/jfs/jfs_txnmgr.c:49:
  include/linux/freezer.h: In function `frozen':
  include/linux/freezer.h:9: error: dereferencing pointer to incomplete type
  include/linux/freezer.h:9: error: `PF_FROZEN' undeclared (first use in this function)
  include/linux/freezer.h:9: error: (Each undeclared identifier is reported only once
  include/linux/freezer.h:9: error: for each function it appears in.)
  ...


From: Cal Peake <cp@absolutedigital.net>

Include include/linux/sched.h in include/linux/freezer.h for PF_FREEZE and 
PF_FROZEN declarations.
