This article [1] describes the -p flag for make(1):
Write to standard output the complete set of macro definitions and
target descriptions. The output format is unspecified.
We already support a similar flag (-d g1), but unlike -p, it still
executes commands. Our implementation just turns it into -d g1, but also
sets flag `printGraphOnly', which will cause make(1) to skip execution.

setting. When the scripts were converted to Bourne shell, this was
removed. The adduser script was changed to use an explicit path for
the pw(8) command so that /usr/sbin did not have to be in the user's
PATH. The rmuser script continued to assume that /usr/sbin was in the
user's path, however. This fixes the rmuser script to use an explicit
path for pw(8) similar to adduser.

to downgrade the exclusive lock to shared one when exclusive lock owner
requested shared lock. New lockmgr panics instead.
The vnode_pager_lock function requests shared lock on the vnode backing
the OBJT_VNODE, and can be called when the current thread already holds
an exlcusive lock on the vnode. For instance, it happens when handling
page fault from the VOP_WRITE() uiomove that writes to the file, with
the faulted in page fetched from the vm object backed by the same file.
We then get the situation described above.
Verify whether the vnode is already exclusively locked by the curthread
and request recursed exclusive vnode lock instead of shared, if true.

I've obtained a draft, <u:> is indeed equivalent to u (to my surprise),
and <th> sorts immediately after z.
The correct ordering is algorithmic (based on the EOR) and can not be
accurately represented as a table.
It seems we only use `lbolt' inside the VFS syncer and the TTY layer
now. Because I'm planning to replace the TTY layer next month, there's
no reason to keep `lbolt' if it's only used in a single thread inside
the kernel.
Because the syncer code wanted to wake up the syncer thread before the
timeout, it called sleepq_remove(). Because we now just use a condvar(9)
with a timeout value of `hz', we can wake it up using cv_broadcast()
without waking up any unrelated threads.

After the import of the new TTY layer, the TTY_QUOTE definition will not
be present anymore. To make sure clists will still work as expected,
introduce an internal definition called QUOTEMASK.
Maybe we can decide to remove the quote bits entirely, but we still have
to look into this. There may be drivers that still use the quote bits.

of saving or restoring the %gs base offset is assigned to the new

sockets for IPv6 raw sockets: separately lock the inpcb for determining
the destination address for a connect()'d raw socket at the rip6_send()
layer, and then re-acquire the inpcb lock in the rip6_output() layer to
query other options on the socket. Previously, the global raw IP socket
lock was used, which while correct and marginally more consistent, could
add significantly to global raw IP socket lock contention.

the default ICMPv6 filter is pass all, test that we can set it to block
