Let filt_fileattach() run without the kernel lock This makes it possible to attach pipe, socket and kqueue event filters without acquiring the kernel lock. Event filters behind vn_kqfilter() are not MP-safe yet, so vn_kqfilter() has to take KERNEL_LOCK(). dmabuf_kqfilter() can skip locking because it has no side effects. OK anton@, mpi@

Move vfs_stall_barrier() from the fd layer into vn_lock() and the vfs layer. vfs stalling is used by suspend/resume and by vmt(4) to stall any filesystem operation from altering the state on disk. All these operations will call vn_lock and be stalled. Adjust vfs_stall_barrier() to allow the lock owner to still progress so that suspend can sync the filesystems after stalling vfs operation.

Unlock lseek(2).

The kernel lock is still required around VOP_GETATTR() as the underlying file system implementations are not MP-safe. ok claudio@

Introduce a global vnode_mtx and use it to make vn_lock() safe to be called without the KERNEL_LOCK. This moves VXLOCK and VXWANT to a mutex protected v_lflag field and also v_lockcount is protected by this mutex. The vn_lock() dance is overly complex and all of this should probably replaced by a proper lock on the vnode but such a diff is a lot more complex. This is an intermediate step so that at least some calls can be modified to grab the KERNEL_LOCK later or not at all. OK mpi@

When a thread tries to exclusively lock a vnode, the same thread must ensure that any other thread currently trying to acquire the underlying vnode lock has observed that the same vnode is about to be exclusively locked.

Make read/write of the f_offset field belonging to struct file MP-safe; as part of the effort to unlock the kernel. Instead of relying on the vnode lock, introduce a dedicated lock per file. Exclusive write access is granted using the new foffset_enter and foffset_leave API. A convenience function foffset_get is also available for threads that only need to read the current offset. The lock acquisition order in vn_write has been changed to match the one in vn_read in order to avoid a potential deadlock. This change also gets rid of a documented race in vn_read(). Inspired by the FreeBSD implementation. With help and ok mpi@ visa@

Fix a bunch of problems and races with posix file locking. - file descriptor table becomes the owner of the lock instead of the proc. - When grabbing the lock, we check if the fd hasn't changed under our feet, this is more or less impossible to solve without a hack like this. I've banged my head against the wall, I figured out a solution, but implementing it correctly would cost me 12 gray hairs. Screw it, this is ugly, but it works. - Wait until usecount drains before releasing the posix lock in closef. - Add missing FREF/FRELE to sys_flock - keep the pid in the flock struct instead of abusing the fact that we used to use the proc as the lock owner. Pointed out by and discussed with Al Viro, big thanks. miod@ ok

FIBMAP ioctl from Linux, only usable on ISO 9660 FS. Note that the lba returned is in 512-byte sectors, so if you're going to use it for things like DVD, you need to divide the result by 4 (for 2048-byte sectors). OK deraadt@

Rename vop_revoke, vn_bwrite, vop_noislocked, vop_nolock, vop_nounlock to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked, vop_generic_lock and vop_generic_unlock. Create vop_generic_abortop and propogate change to all file systems. Fix PR/371. Get rid of locking in NULLFS (should be mostly unnecessary now except for forced unmounts).

Return EINVAL when msg_iovlen or iovcnt <= 0; Make uio_resid unsigned (size_t) and don't return EINVAL if it is < 0 in sys_{read,write}. Remove check for uio_resid < 0 uiomove() now that uio_resid is unsigned and brack remaining panics with #ifdef DIAGNOSTIC. vn_rdwr() must now take a size_t * as its 9th argument so change that and clean up uses of vn_rdwr().
