[PATCH] f2fs: introduce a new direct_IO write path

2013-12-16 Thread Jaegeuk Kim
Previously, f2fs doesn't support direct IOs with high performance which throws every write requests to the buffered write path, resulting in highly performance degradation due to memory opeations like copy_from_user. This patch introduces a new direct IO path in which every write requests are proc
