this time with a small tweak: when flushing the dependencies, don't
update the inode twice, but update once, and then, if needed, fsync it.
Doing so fixes the inode hangs some people were seeing.

in GENERIC so it is not being tested or maintained.

to be co-opted by softdep or not, and use this new interface to inform
softdep in ufs_inactive() that the inode mode has changed.
We don't want to be co-opted there as that might lead to undesired
circular dependencies such as a vput() depending on another vput() to
complete, or a process that is trying to free up a vnode being blocked
trying to acquire a new vnode.
Okay tedu@ deraadt@, thanks to all those who tested.

performance loss issue in some cases when reading past the 2GB boundary in

Appears to fix problems I was seeing with processes stuck with

to free the lock twice. Doesn't actually make any difference for
us (no .o file diff) since the code block that contains the continue
is currently commented out but it makes sense to fix this now so
if/when that code is enabled we don't get bitten. From FreeBSD, ok pedro@.

use mode_t in syscalls.master and to use mode_t in more places in
the kernel. It also makes lint much more useful on kernel code.
I've also added a placeholder for st_birthtime to make a UFS2 import
easier at some future date.

encapsulating all such access into wall-defined functions
that makes sure locking is done as needed.
It also cleans up some uses of wall time vs. uptime some
places, but there is sure to be more of these needed as
well, particularily in MD code. Also, many current calls
to microtime() should probably be changed to getmicrotime(),
or to the {,get}microuptime() versions.

things such that code that only need a second-resolution uptime or wall
time, and used to get that from time.tv_secs or mono_time.tv_secs now get
this from separate time_t globals time_second and time_uptime.

ufs1_daddr_t, a few to daddr_t. ufs_daddr_t typedef is retained, but consider
it deprecated. no functional changes. inspired by freebsd. ok art@

The inheritace is implemented by setting the default vnodeop to a
bypass op that repeats the operation on the spec/fifo vnodeop vector.
The overhead of one extra indirect function call is worth the cleanup
and improved correctness.
This actually solves a few bugs where some vnode ops were missing from
some vectors (like kqfilter or revoke). (and even more on the ubc
branch).
Inspired by the same thing done in FreeBSD.

files up to 16TB, we do limit the max file to 2^31 pages to prevent
overflow of a 32-bit unsigned int. The buffer cache has its own
checks but a little added paranoia never hurts. Adapted from a patch
