Allow EVFILT_VNODE events to work on every filesystem type, not just

2005-06-09T20:20:31+00:00

UFS by:
- Making the pre and post hooks for the VOP functions work even when
DEBUG_VFS_LOCKS is not defined.
- Moving the KNOTE activations into the corresponding VOP hooks.
- Creating a MNTK_NOKNOTE flag for the mnt_kern_flag field of struct
mount that permits filesystems to disable the new behavior.
- Creating a default VOP_KQFILTER function: vfs_kqfilter()

My benchmarks have not revealed any performance degradation.

- Add the character "E" to the understood lock types. This means

   the VOP requires an exclusive lock.

Add VOP_FOO_APV() which takes a pointer to the vop_vector.

This allows stacked or partitioned filesystems to say "Continue
the normal resolution from here", for instace from FFS to UFS.

Use VNASSERT() instead of KASSERT().

Get rid of the VDESC() macro while the pot is boiling anyway, it is

2005-01-13T08:05:20+00:00

only used from generate files now, so we might as well generate the
right stuff from the start.

Change the generated VOP_ macro implementations to improve type checking

2005-01-13T07:53:01+00:00

and KASSERT coverage.

After this check there is only one "nasty" cast in this code but there
is a KASSERT to protect against the wrong argument structure behind
that cast.

Un-inlining the meat of VOP_FOO() saves 35kB of text segment on a typical
kernel with no change in performance.

We also now run the checking and tracing on VOP's which have been layered
by nullfs, umapfs, deadfs or unionfs.

    Add new (non-inline) VOP_FOO_AP() functions which take a "struct
    foo_args" argument and does everything the VOP_FOO() macros
    used to do with checks and debugging code.

    Add KASSERT to VOP_FOO_AP() check for argument type being
    correct.

    Slim down VOP_FOO() inline functions to just stuff arguments
    into the struct foo_args and call VOP_FOO_AP().

    Put function pointer to VOP_FOO_AP() into vop_foo_desc structure
    and make VCALL() use it instead of the current offsetoff() hack.

    Retire vcall() which implemented the offsetoff()

    Make deadfs and unionfs use VOP_FOO_AP() calls instead of
    VCALL(), we know which specific call we want already.

    Remove unneeded arguments to VCALL() in nullfs and umapfs bypass
    functions.

    Remove unused vdesc_offset and VOFFSET().

    Generally improve style/readability of the generated code.

dheader and hheader were the same function, really, so rename one of

2004-12-31T21:12:17+00:00

them to header, kill the other and use both with a different arg...

Use functions to make the program clearer.

Allow -d and -h as command line flags. These are used to generate

2004-12-30T23:18:34+00:00

only the .h or _data.h files respectively.  Restructure code to allow
for this.
