Which is `50`. I saw a few errors like
`Failed to force reset to SHA: object not found!` which seems is
happening because the SHA is not available because there were two
commits pushed almost simultaneously and the second from the top fails
with this error because the SHA is not in the history.

Comments on re-commit from emaste:
Originally committed as fcb4797c90 and reverted in 80a840b8ba due
to the clone operation taking significantly longer. However, I have
seen many failures due to the "object not found" issue recently.
7 of 37 recent runs failed because of this, and intermittent failures
like this makes CI much less useful.
Prefer longer-running runs to intermittent failures.
Pre-r318997 the code looked like:
if (vp->v_mount->mnt_stat.f_fsid.val[0] != (uint32_t)np->n_vattr.na_filesid[0])
vap->va_fsid = (uint32_t)np->n_vattr.na_filesid[0];
Doing this assignment got lost by r318997 and, as such, NFSv4 mounts
of servers with trees of file systems on the server is broken, due to duplicate
fileno values for the same st_dev/va_fsid.
Although I could have re-introduced the assignment, since the value of
na_filesid[0] is not guaranteed to be unique across the server file systems,
I felt it was better to always do the hash for na_filesid[0,1].
Since dev_t (st_dev/va_fsid) is now 64bits, I switched to a 64bit hash.
There is a slight chance of a hash conflict where 2 different na_filesid
values map to same va_fsid, which will be documented in the BUGS
section of the man page for mount_nfs(8). Using a table to keep track
of mappings to catch conflicts would not easily scale to 10,000+ server file
systems and, when the conflict occurs, it only results in fts(3) reporting
a "directory cycle" under certain circumstances.

pmap_promote_l2() failed to handle implementations which set the
accessed and dirty flags. In particular, when comparing the attributes
of a run of 512 PTEs, we must handle the possibility that the hardware
will set PTE_D on a clean, writable mapping.
Following the example of amd64 and arm64, change riscv's
pmap_promote_l2() to downgrade clean, writable mappings to read-only, so
that updates are synchronized by the pmap lock.

When copying mappings from parent to child, we clear the accessed and
dirty bits. This is done for both 4KB and 2MB PTEs. However,
pmap_demote_l2() asserts that writable superpages must be dirty. This
is to avoid races with the MMU setting the dirty bit during promotion
and demotion. pmap_copy() can create clean, writable superpage
mappings, so it violates this assertion.
Modify pmap_copy() to preserve the accessed and dirty bits when copying
2MB mappings, like we do on amd64.

When promoting a run of small mappings to a superpage, we have to
downgrade clean, writable mappings to read-only, to handle the
possibility that the MMU will concurrently mark one of the mappings as
dirty.
The code which performed this operation for the first PTE in the run
used the wrong PTE pointer. As a result, the comparison would always
fail, aborting the promotion. This only occurs when promoting writable,
clean mappings.

During boot we warn that the kbd and openfirm drivers are Giant-locked
and may be deleted. Generally, the warning helps signal that certain
old drivers are not being maintained and are subject to removal, but
this doesn't really apply to certain drivers which are harder to
detangle from Giant.
Add a flag, D_GIANTOK, that devices can specify to suppress the
misleading warning. Use it in the kbd and openfirm drivers.

This is aimed at preventing stacked filesystems like nullfs and unionfs
from "losing" their lower mounts due to forced unmount. Otherwise,
VFS operations that are passed through to the lower filesystem(s) may
crash or otherwise cause unpredictable behavior.
Introduce two new functions: vfs_pin_from_vp() and vfs_unpin().
which are intended to be called on the lower mount(s) when the stacked
filesystem is mounted and unmounted, respectively.
Much as registration in the mnt_uppers list previously did, pinning
will prevent even forced unmount of the lower FS and will allow the
stacked FS to freely operate on the lower mount either by direct
use of the struct mount* or indirect use through a properly-referenced
vnode's v_mount field.
vfs_pin_from_vp() is modeled after vfs_ref_from_vp() in that it uses
the mount interlock coupled with re-checking vp->v_mount to ensure
that it will fail in the face of a pending unmount request, even if
the concurrent unmount fully completes.
Adopt these new functions in both nullfs and unionfs.

Commit d224f05fcf pre-parsed the next operation number for
the put file handle operations. This patch uses this next
operation number, plus the type of the file handle being set by
the put file handle operation, to implement the rules in RFC5661
Sec. 2.6 with respect to replying NFSERR_WRONGSEC.
This patch also adds a check to see if NFSERR_WRONGSEC should be
replied when about to perform Lookup, Lookupp or Open with a file
name component, so that the NFSERR_WRONGSEC reply is done for
these operations, as required by RFC5661 Sec. 2.6.
This patch does not have any practical effect for the FreeBSD NFSv4
client and I believe that the same is true for the Linux client,
since NFSERR_WRONGSEC is considered a fatal error at this time.
