Hello, I'm learning block devices in Linux. It seems submit_bio can be used by file systems to submit block IO requests. But after I search for it in the linux kernel, I didn't see file systems like ext2 and ext3 use it. So how does a file system usually submit a request? I didn't find a wrapper of submit_bio or generic_make_request can be used either.
