Subject: block: switch sync_dirty_buffer() over to WRITE_SYNC
X-Git-Url: http://pilppa.org/gitweb/?a=commitdiff_plain;h=1aa2a7cc6fd7b5c86681a6ae9dfd1072c261a435;p=linux-2.6-omap-h63xx.git

block: switch sync_dirty_buffer() over to WRITE_SYNC

We should now have the logic in place to handle this properly
without regressing on the write performance, so re-enable
the sync writes.
