ad f5ad84fdb3 PR kern/54759 (vm.ubc_direct deadlock when read()/write() into mapping of itself) ... - Add new flag UBC_ISMAPPED which tells ubc_uiomove() the object is mmap()ed somewhere. Use it to decide whether to do direct-mapped copy, rather than poking around directly in the vnode in ubc_uiomove(), which is ugly and doesn't work for tmpfs. It would be nicer to contain all this in UVM but the filesystem provides the needed locking here (VV_MAPPED) and to reinvent that would suck more. - Rename UBC_UNMAP_FLAG() to UBC_VNODE_FLAGS(). Pass in UBC_ISMAPPED where appropriate.		2020-04-23 21:47:07 +00:00
