Subject: [PATCH] jbd2: export __jbd2_debug for modular builds

The commit "jbd2: use a single printk for jbd_debug()" introduced
a new function, __jbd2_debug.  However it needs to be exported
or the final modpost stage of the build will fail with:

  ERROR: "__jbd2_debug" [fs/ext4/ext4.ko] undefined!
  make[1]: *** [__modpost] Error 1
  make: *** [modules] Error 2

Signed-off-by: Paul Gortmaker <>

[Feel free to squash this into the original commit since it is
in your dev branch.]
