  ext4: Add EXT4_IOC_TRIM ioctl to handle batched discard
  fs: Do not dispatch FITRIM through separate super_operation
  ext4: ext4_fill_super shouldn't return 0 on corruption
  jbd2: fix /proc/fs/jbd2/<dev> when using an external journal
  ext4: missing unlock in ext4_clear_request_list()
  ext4: fix setting random pages PageUptodate

There was concern that FITRIM ioctl is not common enough to be included
in core vfs ioctl, as Christoph Hellwig pointed out there's no real point
in dispatching this out to a separate vector instead of just through
->ioctl.

So this commit removes ioctl_fstrim() from vfs ioctl and trim_fs
from super_operation structure.

This really isn't the right thing to do, and strictly speaking we should
have the BKL depth count in the thread info right next to the preempt
count.  The two really do go together.

However, since that would involve a patch to all architectures, and the
BKL is finally going away, it's simply not worth the effort to do the
RightThing(tm).  Just re-instate the <linux/sched.h> include that we
used to get accidentally from the smp_lock.h one.

This is all fallout from the same old "BKL: remove extraneous #include
<smp_lock.h>" commit.

jiffies is defined as "volatile".

  extern unsigned long volatile __jiffy_data jiffies;

ACCESS_ONCE() uses "volatile".
As a result, some compilers warn duplicate `volatile' for ACCESS_ONCE(jiffies).

Commit 451a3c24b013 ("BKL: remove extraneous #include <smp_lock.h>")
removed the #include line that was the only thing that was surrounded by
the #ifdef/#endif.

So now that #ifdef is guarding nothing at all. Just remove it.
