J. Bruce Fields fa0a21269f nfsd: bypass readahead cache when have struct file ... The readahead cache compensates for the fact that the NFS server currently does an open and close on every IO operation in the NFSv2 and NFSv3 case. In the NFSv4 case we have long-lived struct files associated with client opens, so there's no need for this. In fact, concurrent IO's using trying to modify the same file->f_ra may cause problems. So, don't bother with the readahead cache in that case. Note eventually we'll likely do this in the v2/v3 case as well by keeping a cache of struct files instead of struct file_ra_state's.
