History
Chris Mason 398c95bdf2 try to reap reiserfs pages left around by invalidatepage 
reiserfs_invalidatepage will refuse to free pages if they have been logged
in data=journal mode, or were pinned down by a data=ordered operation.  For
data=journal, this is fairly easy to trigger just with fsx-linux, and it
results in a large number of pages hanging around on the LRUs with
page->mapping == NULL.

Calling try_to_free_buffers when reiserfs decides it is done with the page
allows it to be freed earlier, and with much less VM thrashing.  Lock
ordering rules mean that reiserfs can't call lock_page when it is releasing
the buffers, so TestSetPageLocked is used instead.  Contention on these
pages should be rare, so it should be sufficient most of the time.
