| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Back when VOP_* was introduced, we did not have new-style structphk2004-12-011-15/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | initializations but we did have lofty goals and big ideals. Adjust to more contemporary circumstances and gain type checking. Replace the entire vop_t frobbing thing with properly typed structures. The only casualty is that we can not add a new VOP_ method with a loadable module. History has not given us reason to belive this would ever be feasible in the the first place. Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc. Give coda correct prototypes and function definitions for all vop_()s. Generate a bit more data from the vnode_if.src file: a struct vop_vector and protype typedefs for all vop methods. Add a new vop_bypass() and make vop_default be a pointer to another struct vop_vector. Remove a lot of vfs_init since vop_vector is ready to use from the compiler. Cast various vop_mumble() to void * with uppercase name, for instance VOP_PANIC, VOP_NULL etc. Implement VCALL() by making vdesc_offset the offsetof() the relevant function pointer in vop_vector. This is disgusting but since the code is generated by a script comparatively safe. The alternative for nullfs etc. would be much worse. Fix up all vnode method vectors to remove casts so they become typesafe. (The bulk of this is generated by scripts)

* Clean up the stub fake vnode locking implemenations. The main reason thispeter2004-03-291-0/+9
| | | | | | | | | | | | stuff was here (NFS) was fixed by Alfred in November. The only remaining consumer of the stub functions was umapfs, which is horribly horribly broken. It has missed out on about the last 5 years worth of maintenence that was done on nullfs (from which umapfs is derived). It needs major work to bring it up to date with the vnode locking protocol. umapfs really needs to find a caretaker to bring it into the 21st century. Functions GC'ed: vop_noislocked, vop_nolock, vop_nounlock, vop_sharedlock.

| | | | | | | | | | | | v_tag is now const char * and should only be used for debugging. Additionally: 1. All users of VT_NTS now check vfsconf->vf_type VFCF_NETWORK 2. The user of VT_PROCFS now checks for the new flag VV_PROCDEP, which is propagated by pseudofs to all child vnodes if the fs sets PFS_PROCDEP.

| | | | | | | | | | | | | | | it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.
