Revert "cfq: Remove special treatment for metadata rqs."
We have a kernel build regression since 3.1-rc1, which is about 10% regression. The kernel source is in an ext3 filesystem. Alex Shi bisect it to commit: commit a07405b7802691d29ab3b23bdc76ee6d006aad0b Author: Justin TerAvest <teravest@google.com> Date: Sun Jul 10 22:09:19 2011 +0200 cfq: Remove special treatment for metadata rqs. Apparently this is caused by lack metadata preemption, where ext3/ext4 do use READ_META. I didn't see a way to fix the issue, so suggest reverting the patch. This reverts commit a07405b7802691d29ab3b23bdc76ee6d006aad0b. Reported-by: Alex Shi<alex.shi@intel.com> Reported-by: Shaohua Li<shaohua.li@intel.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
