init in the init method. Give malloc types the same treatment.
Makes file systems nicer to work with in linksetless environments
and fixes a few LKM discrepancies.
the reference counter of the corresponding struct dquot will overflow.
Change the type of the reference counter from u_int16_t to u_int32_t and
add an assertion to check for overflow.

Welcome to 4.99.21 (struct dquot and therefore struct inode changed layout)
Adjust fs->fs_maxfilesize instead of ump->um_maxfilesize
in ffs_oldfscompat_read() because the latter is overrided
by the former after ffs_oldfscompat_read() returned.
Fixes EFBIG errors on read(2) and "exec /sbin/init: error 8"

Froyen, patch posted/tested by Blair Sadewitz.
the "smooth" syncer, as if vfs.sync.*delay = 0, but only for LFS. The
default is "on", i.e., ignore lazy sync.
Reduce the amount of polling/busy-waiting done by lfs_putpages(). To
accomplish this, copied genfs_putpages() and modified it to indicate which
page it was that caused it to return with EDEADLK. fsync()/fdatasync()
should no longer ever fail with EAGAIN, and should not consume huge
quantities of cpu.
Also, try to make dirops less likely to be written as the result of a
VOP_PUTPAGES(), while ensuring that they are written regularly.

Revert softdep_trackbufs() to its state before vn_start_write() was added.
Remove from struct mount now unneeded flags IMNT_SUSPEND* and
members mnt_writeopcountupper, mnt_writeopcountlower and mnt_leaf.
Welcome to 4.99.17
P_*/L_* naming convention, and rename the in-kernel flags to avoid
conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD
constant.
Restores source compatibility with pre-newlock2 tools like ps or top.

Patch by Slava Semushin <slava.semushin@gmail.com>
Again, this was tested by comparing obj files from a pristine and a patched
source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs,
src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers
were detected in 'objdump -d' output.
The suspension helpers are now put into file system specific operations.
This means every file system not supporting these helpers cannot be suspended
and therefore snapshots are no longer possible.
Implemented for file systems of type ffs.
The new API is enabled on a kernel option NEWVNGATE. This option is
not enabled by default in any kernel config.
Presented and discussed on tech-kern with much input from
Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>.
Welcome to 4.99.9 (new vfs op vfs_suspendctl).
- finish implementing splraiseipl (and makeiplcookie).
http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html
- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
