Subject: [PATCH v2 4/4] NFS: Remove remaining dfprintks related to fscache and remove NFSDBG_FSCACHE
Date: Fri, 17 Dec 2021 12:54:25 -0500	[thread overview]
Message-ID: <1639763665-4917-5-git-send-email-dwysocha@redhat.com> (raw)
In-Reply-To: <1639763665-4917-1-git-send-email-dwysocha@redhat.com>

The fscache cookie APIs including fscache_acquire_cookie() and
fscache_relinquish_cookie() now have very good tracing.  Thus,
there is no real need for dfprintks in the NFS fscache interface.

The NFS fscache interface has removed all dfprintks so remove the
NFSDBG_FSCACHE defines.
