* Remove the unused olddp parameter from function dounmount().bluhm2017-01-101-2/+2
| | | | OK mpi@ millert@
* When vfs_busy() is sleeping, it uses RW_SLEEPFAIL and will fail.bluhm2016-03-121-3/+6
| | | | | | | | So if vop_generic_revoke() does not unmount because the mount point is busy, this could result in a mount point without a valid device. It is better to check and sleep in a loop to avoid a corrupt mount point. OK natano@ krw@

* Introduce vop_generic_bmap(); use it where applicable.thib2008-05-031-1/+16
| | | | | | | | one thing of note, fifofs changes in that its bmap now sets the runp too 0, but that was an oversight in the old code. ok art@
* fifofs, deadfs and specfs all have the same "trivial lookup routine thatthib2007-12-271-1/+11
| | | | | | | always fails". Introduce vop_generic_lookup(), which is a trivial lookup routine that always fails and use that instead, zap the redundant copies. ok toby@, tedu@, art@
* Allow to pull out an usb stick with ffs filesystem while mountedbluhm2007-09-151-1/+13
| | | | | | | | | | | | | | | | and a file is written onto the stick. Without these fixes the machine panics or hangs. The usb fix calls the callback when the stick is pulled out to free the associated buffers. Otherwise we have busy buffers for ever and the automatic unmount will panic. The change in the scsi layer prevents passing down further dirty buffers to usb after the stick has been deactivated. In vfs the automatic unmount has moved from the function vgonel() to vop_generic_revoke(). Both are called when the sd device's vnode is removed. In vgonel() the VXLOCK is already held which can cause a deadlock. So call dounmount() earlier. ok krw@, I like this marco@, tested by ian@

* Remove the v_interlock simplelock from the vnode structure.thib2007-03-211-19/+1
| | | | | | | | | Zap all calls to simple_lock/unlock() on it (those calls are #defined away though). Remove the LK_INTERLOCK from the calls to vn_lock() and cleanup the filesystems wich implement VOP_LOCK(). (by remvoing the v_interlock from there calls to lockmgr()). ok pedro@, art@, tedu@

* in theory, vnlock should alays be NULL in the generic lock (sic) functions.tedu2004-06-091-23/+3

| | | | | | | | | machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.
* Big cleanup inspired by NetBSD with some parts of the code from NetBSD.art2001-12-101-684/+2
| | | | | | | | - get rid of VOP_BALLOCN and VOP_SIZE - move the generic getpages and putpages into miscfs/genfs - create a genfs_node which must be added to the top of the private portion of each vnode for filsystems that want to use genfs_{get,put}pages - rename genfs_mmap to vop_generic_mmap
