Andreas Kling	07425580a8	Kernel: Put all Regions on InlineLinkedLists (separated by user/kernel) ... Remove the global hash tables and replace them with InlineLinkedLists. This significantly reduces the kernel heap pressure from doing many small mmap()'s.	2019-08-08 11:11:22 +02:00
Andreas Kling	b67200dfea	Kernel: Use a FixedArray for VMObject::m_physical_pages ... This makes VMObject 8 bytes smaller since we can use the array size as the page count. The size() is now also computed from the page count instead of being a separate value. This makes sizes always be a multiple of PAGE_SIZE, which is sane.	2019-08-07 20:12:50 +02:00
Andreas Kling	6bdb81ad87	Kernel: Split VMObject into two classes: Anonymous- and InodeVMObject ... InodeVMObject is a VMObject with an underlying Inode in the filesystem. AnonymousVMObject has no Inode. I'm happy that InodeVMObject::inode() can now return Inode& instead of VMObject::inode() return Inode*. :^)	2019-08-07 18:09:32 +02:00
