[PATCH tip/core/rcu 27/48] vfs: add fs.h to define struct file
The sparse RCU-pointer annotations require definition of the underlying type of any pointer passed to rcu_dereference() and friends. So fcheck_files() needs "struct file" to be defined, so include fs.h. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> Signed-off-by: Paul E.

From: Lai Jiangshan <laijs(a)cn.fujitsu.com> There is no need to disable lockdep after an RCU lockdep splat, so remove the debug_lockdeps_off() from lockdep_rcu_dereference(). To avoid repeated lockdep splats, use a static variable in the inlined rcu_dereference_check() and rcu_dereference_protected() macros so tha... 4 May 2010 16:49
