Linus Torvalds ebeaa8ddb3 Revert "jbd2: speedup jbd2_journal_dirty_metadata()" 
This reverts commit 2143c1965a.

This commit seems to be the cause of the following jbd2 assertion
failure:

which is not easily reproducible (I've seen it just once, and then Ted
was able to reproduce it once).  Revert it while Ted and Jan try to
figure out what is wrong.
