[PATCH] reiserfs: reiserfs hang and performance fix for data=journal mode
In data=journal mode, reiserfs writepage needs to make sure not to trigger
transactions while being run under PF_MEMALLOC. This patch makes sure to
redirty the page instead of forcing a transaction start in this case.
Also, calling filemap_fdata* in order to trigger io on the block device can
cause lock inversions on the page lock. Instead, do simple batching from
flush_commit_list.
