of its lost+found directory by allocating direct block pointers. The
effect was that it was limited to about 19,000 files. One of Peter Holm's
tests produced a filesystem with about 23,000 lost files which meant
that fsck_ffs was unable to recover it. This update allows lost+found
to be expanded into a single indirect block which allows it to store
up to about 6,573,000 lost files.

POSIX AIO is great, but it lacks vectored I/O functions. This commit
fixes that shortcoming by adding aio_writev and aio_readv. They aren't
part of the standard, but they're an obvious extension. They work just
like their synchronous equivalents pwritev and preadv.
It isn't yet possible to use vectored aiocbs with lio_listio, but that
could be added in the future.

PR#252358 reported a serious performance problem w.r.t.
cp(1) when copying large non-sparse files.
This problem appears to have been caused by cp(1)
calling copy_file_range(2) with a small "len" argument.
This patch adds a recommendation to use a large "len"
value where possible, for performance reasons.

PR252358 reported a serious performance problem when
copying a large non-sparse file on a UFS file system.
This problem seems to have been caused by a large
number of SEEK_HOLE operations, with one done
for each copy_file_range(2) call.
This patch modifies cp(1) to use a large (SSIZE_MAX)
len argument, reducing the number of system calls
and resolving the performance issue.
While here, convert the type of the "rcount" from "int"
to "ssize_t" so that it is consistent with that returned
by both read(2) and copy_file_range(2).

In particular, do not assume that vn_start_write() returns the same mp
as it was passed in, or never returns error.
Also be more accurate to return NULL vp and mp when error occured, to
catch wrong control flow easier.
Stop checking for NULL mp before calling vn_finished_write(), NULL mp
is handled transparently by the function.

Commit 774a36851e fixed the NFS server so that it could handle
ERELOOKUP returns from VOP calls by redoing the operation/RPC.
However, for NFSv4.0, redoing an Open would increment
the open_owner's seqid multiple times, breaking the protocol.
This patch sets a new flag called ND_ERELOOKUP on the RPC when
a redo is in progress. Then the code that increments the seqid
avoids the seqid increment/check when the flag is set, since
it indicates this has already been done for the Open.
r367672 modified UFS such that certain VOPs, such as
VOP_CREATE() will intermittently return ERELOOKUP.
When this happens, the entire system call, or NFS
operation in the case of the NFS server, must be redone.
This patch adds that support to the NFS server by rolling
back the state of the NFS request arguments and NFS
reply arguments mbuf lists to the condition they were
in before the operation and then redoing the operation.

If any PHI nodes in loop exit blocks have incoming values from the
loop that are accesses of TLS variables with local dynamic or general
dynamic TLS model, the address will be computed inside the loop.
Since this includes a call to __tls_get_addr, this will in turn cause
the CTR loops verifier to complain. Disable CTR loops in such cases.

Previously having ficl/liblua in LIB32LIST with their respective option
turned OFF would be relatively harmless, as we wouldn't act on it unless we
were building the non-32 variant. As of ac5f382a9d, however, these are
now used for dependencies in some cases and must reflect what's actually
going to be built.
The change to kern_jail_set that was supposed to "also properly clean
up when attachment fails" didn't fix a memory leak but actually caused
a double free. Back that part out, and leave the part that manages
allprison_lock state.
