From: Chuck Lever <chuck.lever@xxxxxxxxxx> Mike has expressed interest in making NFSD perform direct, uncached, or asynchronous I/O, independent of how the target file might have been opened by the file cache. To do that, the idea is to pass in RWF_ flags during each VFS read and write. However, Christoph suggested APIs that already exist which streamline the I/O operation a bit and expose the per-I/O flag setting directly. The suggestion looks to me like a straightforward and sensible general clean up of these code paths. This series refactors nfsd_iter_read() and nfsd_vfs_write() to use those APIs instead of vfs_iter_read() and vfs_iter_write(), respectively, as a first baby step down this path. No behavior change is expected.
