* Change the generated VOP_ macro implementations to improve type checkingPoul-Henning Kamp2005-01-131-48/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) Notes: svn path=/head/; revision=138290

| | | | | | | | | | | | | | | | | | | in the VOP inlines. This is intended to replace the simple locking specifications for calls that have more complicated behavior such as rename and lookup. The syntax of the new entries is: #! name pre/post function If the function is marked 'pre' it is executed prior to calling the VOP and takes a pointer to a struct vop_{name}_args as it's only parameter. If the function is marked 'post' it is executed after the VOP call and takes a pointer to a struct vop_{name}_args as it's first parameter and the integer return value from the vop as the second paramter.

* Update this to be able to output ASSERT_VOP_(UN)LOCKED() based on theEivind Eklund1999-09-261-255/+230
| | | | | | | | | | | | | | | | | lock specifications in kern/vnode_if.src. At present, this do not distinguish between exclusive and shared locks, and the kernel is so full of bugs in this area that running with auto-generation of assertions enabled makes DEBUG_VFS_LOCKS totally useless for anybody that has used it for anything prior to outputting automated assertions. Due to this, I made vnode_if.sh only output locking assertions if you have the environment variable DEBUG_ALL_VFS_LOCKS set to "YES". In order to actually use the assertions, you need to also add "options DEBUG_VFS_LOCKS" to your kernel config file. Urged to commit by: phk Notes: svn path=/head/; revision=51681

* Make the vnode opv vector construction fully dynamic. Previously wePeter Wemm1998-11-101-38/+2
| | | | | | | | | | | | | | | | | | | | | | | leaked memory on each unload and were limited to items referenced in the kernel copy of vnode_if.c. Now a kernel module is free to create it's own VOP_FOO() routines and the rest of the system will happily deal with it, including passthrough layers like union/umap/etc. Have VFS_SET() call a common vfs_modevent() handler rather than inline duplicating the common code all over the place. Have VNODEOP_SET() have the vnodeops removed at unload time (assuming a module) so that the vop_t ** vector is reclaimed. Slightly adjust the vop_t ** vectors so that calling slot 0 is a panic rather than a page fault. This could happen if VOP_something() was called without *any* handlers being present anywhere (including in vfs_default.c). slot 1 becomes the default vector for the vnodeop table.
