Sepherosa Ziehau [Thu, 14 May 2009 10:44:51 +0000 (18:44 +0800)]
Use nq version of systimer_init_periodic() when initialize interrupt
livelock avoidance systimer.

The bug revealed itself as long time looping in the systimer_intr():
The one shot timer interrupt handler is prevented from running for
some time probably due to heavy interrupt load, and livelock avoidance
systimer is setup using high frequency (40000Hz by default).  If non-nq
version of systimer was used, then the main loop of systimer_intr()
would try to keep running and reloading this systimer until the
accumulated time caught up with the saved sys_cputimer count.

helped to locate the systimer cause the long time looping.

Add kernel-layer support for chflags checks, remove (most) from the VFS layer.

Give nlookup() and nlookup_va() the tools to do nearly all chflags related
activities.  Here are the rules:

Immutable (uchg, schg)

    If set on a directory no files associated with the directory may
    be created, deleted, linked, or renamed.  In addition, any files open()ed
    via the directory will be immutable whether they are flagged that
    way or not.

    If set on a file or directory the file or directory may not be
    written to, chmodded, chowned, chgrped, or renamed.  The file can
    still be hardlinked and the file/directory can still be chflagged.
    If you do not wish the file to be linkable then set the immutable bit
    on all directories containing a link of the file.  Once you form
    this closure no further links will be possible.

    NOTE ON REASONING:  Security scripts should check link counts anyway,
    depending on a file flag which can be changed as a replacement for
    checking the link count is stupid.  If you are secure then your closures
    will hold.  If you aren't then nothing will save you.

    This feature is not recursive.  If the directory contains
    subdirectories they must be flagged immutable as well.

Undeletable (uunlnk, sunlnk)

    If set on a file or directory that file or directory cannot be removed
    or renamed.  The file can still otherwise be manipulated, linked, and
    so forth.  However, it should be noted that any hardlinks you create
    will also not be deletable :-)

    If set on a directory this flag has no effect on the contents
    of the directory (yet).  See APPEND-ONLY on directories for what
    you want.

Append-only (uappnd/sappnd)

    If set on a directory no file within the directory may be deleted or
    renamed.  However, new files may be created in the directory and
    the files in the directory can be modified or hardlinked without
    restriction.

    If set on a file the file cannot be truncated, random-written, or
    deleted.  It CAN be chmoded, chowned, renamed, and appended to
    with O_APPEND etc.

    If you do not wish the file to be renameable then you must also
    set the Undeletable flag.  Setting the append-only flag will ensure
    that the file doesn't disappear from the filesystem, but does not
