Subject: [PATCH 0/1] Convert nfs_readpages() to nfs_readahead()
Date:   Thu,  7 Oct 2021 19:32:07 -0400
Message-Id: <1633649528-1321-1-git-send-email-dwysocha@redhat.com>
Precedence: bulk

This patch converts nfs_readpages() to nfs_readahead().  It was
applied on top of the set I just posted [1] plus Chuck's v1 patch to
convert dfprintks to tracepoints [2].  It is being tested on top of
these patches at BakeAThon against various servers, cthon, xfstests,
and my fscache unit tests.  Note that Chuck may post a v3 of his
patch and this would need rebased on that patch.

Note that a nfs-utils patch will need to be done to properly account
for the changed NFSIOS_* counters.

I would consider this a "nice to have" for this cycle but I wanted
to get it out there sooner than later.  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.
