[PATCH] ext4: fix ext4_dirty_inode() compile warning

[PATCH] ext4: fix ext4_dirty_inode() compile warning

[Curt Wohlgemuth]

Hi Ted:

Apparently my patch for

   ext4: Make sure ext4_dirty_inode() updates the inode in no journal mode

didn't play well if CONFIG_JBD_DEBUG wasn't defined.

Here are two patches that fix it.  I don't know if the jbd_debug() call has
any importance or not; you can choose which is better perhaps?

Thanks,
Curt

==============================================

Remove jbd_debug() call from ext4_inode_dirty()

Make sure ext4_inode_dirty() compiles if CONFIG_JBD_DEBUG is not defined.

I chose the first one, with a slightly elaborated commit message.

Thanks,
