sysent' for a new system call into a new MAKE_SYSENT() macro.
- Use MAKE_SYSENT() to build a full sysent for the nfssvc system call in
the NFS server and use syscall_register() and syscall_deregister() to
manage the nfssvc system call entry instead of manually frobbing the
sysent[] array.
file descriptor is closed out from under us in kern_open(). This race
is already handled and the file will be closed when kern_open() does an
fdrop just before returning.
and had no chance to match it by the 2nd address precisely.
Otherwise the unclosed range would bogusly extend to the end
of stream.
Add a basic regression test for the bug fixed. (This change
also fixes the more complex case 5.3 from `multitest.t'.)

in a more reasonable way than BSD sed does: they properly
close the range even if we branched over its end. No doubt,
the range `1,5' should not match lines from 9 through 14.
in parentheses. The ?: operator has a remarkably low precedence, so
expressions like (MATCH(foo) && bar) would have an unexpected meaning
w/o the parentheses around MATCH().

skip over the end-of-entry padding instead of reading and discarding
it.
Considering that tar files normally have a block size of 10kB, this
isn't likely to avoid reading any data, but at least it makes the code
simpler and clearer.
execution should help us avoiding potential deadlock and illegal locking
while sleeping in various mixer -> usb calls. To enable it, use
hint.uaudio.%d.async="1" or sysctl dev.uaudio.%d.async=1. Default is
disable, to remain compatible with old behaviour (with slight risk of
potential deadlock).
When the linux port changes were imported which split the
target command list to be separate from the initiator command
list and the handle format changed to encode a type in the handle
the implications to the function isp_handle_index (which only
the NetBSD/OpenBSD/FreeBSD ports use) were overlooked.
The fault is twofold: first, the index into the DMA maps
in isp_pci is wrong because a target command handle with
the type bit left in place caused a bad index (and panic)
into dma map. Secondly, the assumption of the array
of DMA maps in either PCS or SBUS attachment structures is
that there is a linear mapping between handle index and
DMA map index. This can no longer be true if there are
overlapping index spaces for initiator mode and target
mode commands.
These changes bandaid around the problem by forcing us
to not have simultaneous dual roles and doing the appropriate
masking to make sure things are indexed correctly. A longer
term fix is being devloped.
them are related to the `c' function's need to know if we are at
the actual end of the address range. (It must print the text not
earlier than the whole pattern space was deleted.) It appears the
only sed function with this requirement.
There is `lastaddr' set by applies(), which is to notify the `c'
function, but it can't always help because it's false when we are
hitting the end of file early. There is also a bug in applies()
due to which `lastaddr' isn't set to true on degenerate ranges such
as `$,$' or `N,$' if N appears the last line number.
Handling early EOF condition in applies() could look more logical,
but it would effectively revert sed to the unreasonable behaviour
rev. 1.26 of main.c fought against, as it would require lastline()
be called for each line within each address range. So it's better
to call lastline() only if needed by the `c' function.
Together with this change to sed go regression tests for the bugs
fixed (c1-c3). A basic test of `c' (c0) is also added as it helped
me to spot my own error.

vfs_flags field is used for VFCF_* flags which are given at file system
driver creation time (via VFS_SET(9)) macro.
What this code did was bascially this:
If file system registers itself with VFCF_UNICODE flag (stores file names
as Unicode), it will gain MNT_SOFTDEP flag (UFS soft-updates).
If file system registers itself with VFCF_LOOPBACK flag (aliases some other
mounted FS), it will gain MNT_SUIDDIR flag (special handling of SUID on
dirs).
The latter will be quite dangerous, but those flags are reset later in
vfs_domount().
