f2fs: add REQ_META about metadata requests for submit
Adding REQ_META for all the metadata requests can help in improving the FS performance, if the underlying device supports TAGGING. So, when considering the submit_bio path for all the f2fs requests. We can add REQ_META for all the META requests. As a precursor to this change we considered the commit 4265900e0be653f5b78baf2816857ef57cf1332f 'mmc: MMC-4.5 Data Tag Support' Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com> Signed-off-by: Amit Sahrawat <a.sahrawat@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
