This patch converts nfs_readpages() to nfs_readahead(). It was applied as follows: 0. Start with trond's testing branch at 0abb8895b065 NFS: Fix an Oops in pnfs_mark_request_commit() 1. Apply David Howells v3 of "fscache: Replace and remove old I/O API" [1] 2. Apply my fscache patches v2 of "Various NFS fscache cleanups" [2] 3. Apply Chucks v3 of "NFS: Replace dprintk callsites in nfs_readpage(s)" plus one fixup (remove the "read_complete:" label in last hunk, which conflicts with #2) [3] 4. Apply this patch So far the existing BakeAThon tests have gone well with no oops or any failure differences in xfstests (generic) between 5.15.0-rc4 and kernel with #2 and #3 above. I will continue testing now with all patches as described above (#1 - #5). As far as I know this has been an outstanding item for the NFS client for a while and the fscache fallback IO API clears the way for this patch. I also just posted a v2 of the nfs-utils patch to display a "VFS readahead" count rather than a readpages count [4].
