[PATCH] Fix try_to_free_buffer() locking
Fix commit ecdfc9787fe527491baefc22dce8b2dbd5b2908d
Not to put too fine a point on it, but in a nutshell...
__set_page_dirty_buffers() | try_to_free_buffers()
---------------------------+---------------------------
| spin_lock(private_lock);
| drop_bufers()
| spin_unlock(private_lock);
spin_lock(private_lock) |
!page_has_buffers() |
spin_unlock(private_lock) |
SetPageDirty() |
| cancel_dirty_page()
oops!
