* Include <sys/vmmeter.h> directly instead of relying on it beingmpi2014-05-061-6/+3
| | | | | | | | | | | | | | pulled by <uvm/uvm_extern.h> and turn uvm_total() into a private function. The preferred way to get memory stats is through the VM_UVMEXP sysctl(3) since VM_METER is just a wrapper on top of it. In the kernel, use `uvmexp' directly instead of uvm_total(). This change does not remove <sys/vmmeter.h> from <uvm/uvm_extern.h> to give some more time to port maintainers to fix their ports. ok guenther@ as part of a larger diff.

* Unset fuse_mnt in fusefs_unmount after vflushing and freeing fbufs in use.pelikan2013-12-103-10/+10
| | | | | | | | This way, if fuse unmounts a FS without FBT_DESTROY, the fuse_mnt pointer is already invalidated. Also, on weird unmount situations with vnodes in use, vflush() them before doing fuse_device_cleanup(). Tested with ntfs-3g, ok syl@.

| | | | | | | | | | | | | the special provided when the mount was requested. This may be the same as the special that was actually used for the mount (e.g. in the case of a device node) or it may be different (e.g. in the case of a DUID). Whilst here, change f_ctime to a 64 bit type and remove the pointless f_spare members. Compatibility goo courtesy of guenther@ ok krw@ millert@

| | | | | | | | | | | _PC_PRIO_IO, and _PC_SYNC_IO names in VOP_PATHCONF(), as they're fs-independent for us. Since we don't support latter three on any fs, we can also define the related _POSIX_{ASYNC,PRIO,SYNC}_IO symbols in <unistd.h> (via sys/unistd.h) with value -1. Also, zap pointless tty-only values from procfs(!). ok beck@, deraadt@
* Cleanup VFS mount string handling:jsing2012-09-101-5/+4
| | | | | | | | | | | - Avoid using copyinstr() without checking the return value. - sys_mount() has already copied the path in, so pass this to the filesystem mount code so that it does not have to copy it in again. - Avoid copyinstr()/bzero() dance when we can simply bzero() and strlcpy(). ok krw@
