Chuck Lever 57927de983 NFSD: Trace boot verifier resets 
[ Upstream commit 75acacb6583df0b9328dc701d8eeea05af49b8b5 ]

According to commit bbf2f098838a ("nfsd: Reset the boot verifier on
all write I/O errors"), the Linux NFS server forces all clients to
resend pending unstable writes if any server-side write or commit
operation encounters an error (say, ENOSPC). This is a rare and
quite exceptional event that could require administrative recovery
action, so it should be made trace-able. Example trace event:

nfsd-938   [002]  7174.945558: nfsd_writeverf_reset: boot_time=        61cc920d xid=0xdcd62036 error=-28 new verifier=0x08aecc6142515904

[ cel: adjusted to apply to v5.10.y ]
