* Remove the struct thread unuseful argument from bufobj interface.attilio2008-10-101-3/+3
| | | | | | | | | | | | | | | | | | | | | In particular following functions KPI results modified: - bufobj_invalbuf() - bufsync() and BO_SYNC() "virtual method" of the buffer objects set. Main consumers of bufobj functions are affected by this change too and, in particular, functions which changed their KPI are: - vinvalbuf() - g_vfs_close() Due to the KPI breakage, __FreeBSD_version will be bumped in a later commit. As a side note, please consider just temporary the 'curthread' argument passing to VOP_SYNC() (in bufsync()) as it will be axed out ASAP Reviewed by: kib Tested by: Giovanni Trematerra <giovanni dot trematerra at gmail dot com>

* Cleanup lockmgr interface and exported KPI:attilio2008-01-242-6/+4
| | | | | | | | | | | | | | | | | | | | - Remove the "thread" argument from the lockmgr() function as it is always curthread now - Axe lockcount() function as it is no longer used - Axe LOCKMGR_ASSERT() as it is bogus really and no currently used. Hopefully this will be soonly replaced by something suitable for it. - Remove the prototype for dumplockinfo() as the function is no longer present Addictionally: - Introduce a KASSERT() in lockstatus() in order to let it accept only curthread or NULL as they should only be passed - Do a little bit of style(9) cleanup on lockmgr.h KPI results heavilly broken by this change, so manpages and FreeBSD_version will be modified accordingly by further commits.

| | | | | | | | | | | conjuction with 'thread' argument passing which is always curthread. Remove the unuseful extra-argument and pass explicitly curthread to lower layer functions, when necessary. KPI results broken by this change, which should affect several ports, so version bumping and manpage update will be further committed. Tested by: kris, pho, Diego Sardina <siarodx at gmail dot com>

| | | | | | | | | | | | | | | | Remove this argument and pass curthread directly to underlying VOP_LOCK1() VFS method. This modify makes the code cleaner and in particular remove an annoying dependence helping next lockmgr() cleanup. KPI results, obviously, changed. Manpage and FreeBSD_version will be updated through further commits. As a side note, would be valuable to say that next commits will address a similar cleanup about VFS methods, in particular vop_lock1 and vop_unlock.

* Remove explicit calling of lockmgr() with the NULL argument.attilio2008-01-081-2/+4
| | | | | | | | | | | | | | | | | | Now, lockmgr() function can only be called passing curthread and the KASSERT() is upgraded according with this. In order to support on-the-fly owner switching, the new function lockmgr_disown() has been introduced and gets used in BUF_KERNPROC(). KPI, so, results changed and FreeBSD version will be bumped soon. Differently from previous code, we assume idle thread cannot try to acquire the lockmgr as it cannot sleep, so loose the relative check[1] in BUF_KERNPROC(). Tested by: kris [1] kib asked for a KASSERT in the lockmgr_disown() about this condition, but after thinking at it, as this is a well known general rule, I found it not really necessary.

| | | | | | | | | | | | | | | | | | | | | | | late stages of unmount). On failure, the vnode is recycled. Add insmntque1(), to allow for file system specific cleanup when recycling vnode on failure. Change getnewvnode() to no longer call insmntque(). Previously, embryonic vnodes were put onto the list of vnode belonging to a file system, which is unsafe for a file system marked MPSAFE. Change vfs_hash_insert() to no longer lock the vnode. The caller now has that responsibility. Change most file systems to lock the vnode and call insmntque() or insmntque1() after a new vnode has been sufficiently setup. Handle failed insmntque*() calls by propagating errors to callers, possibly after some file system specific cleanup. Approved by: re (kensmith) Reviewed by: kib In collaboration with: kib
* Move vnode-to-file-handle translation from vfs_vptofh to vop_vptofh method.pjd2007-02-152-18/+20
| | | | | | | | | | | | | | | | This way we may support multiple structures in v_data vnode field within one file system without using black magic. Vnode-to-file-handle should be VOP in the first place, but was made VFS operation to keep interface as compatible as possible with SUN's VFS. BTW. Now Solaris also implements vnode-to-file-handle as VOP operation. VFS_VPTOFH() was left for API backward compatibility, but is marked for removal before 8.0-RELEASE.

* I ran into an nfs client panic a couple of times in a row over thealfred2006-01-171-1/+5
| | | | | | | | | | | | | | | | | | | | last few days. I tracked it down to the fact that nfs_reclaim() is setting vp->v_data to NULL _before_ calling vnode_destroy_object(). After silence from the mailing list I checked further and discovered that ufs_reclaim() is unique among FreeBSD filesystems for calling vnode_destroy_object() early, long before tossing v_data or much of anything else, for that matter. The rest, including NFS, appear to be identical, as if they were just clones of one original routine. The enclosed patch fixes all file systems in essentially the same way, by moving the call to vnode_destroy_object() to early in the routine (before the call to vfs_hash_remove(), if any). I have only tested NFS, but I've now run for over eighteen hours with the patch where I wouldn't get past four or five without it.

* Normalize a significant number of kernel malloc type names:rwatson2005-10-311-2/+2
| | | | | | | | | | | | | | | | | | | - Prefer '_' to ' ', as it results in more easily parsed results in memory monitoring tools such as vmstat. - Remove punctuation that is incompatible with using memory type names as file names, such as '/' characters. - Disambiguate some collisions by adding subsystem prefixes to some memory types. - Generally prefer lower case to upper case. - If the same type is defined in multiple architecture directories, attempt to use the same name in additional cases. Not all instances were caught in this change, so more work is required to finish this conversion. Similar changes are required for UMA zone names.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
