2019-11-04	Kernel: Make File's can_read/can_write take a const FileDescription&	Andreas Kling
	Asking a File if we could possibly read or write it will never mutate the asking FileDescription&, so it should be const.
2019-09-04	Kernel: Remove unused gunk from PATADiskDevice	Andreas Kling

2019-08-21	Kernel: Move DiskDevice::block_size() up to BlockDevice	Andreas Kling
	All block devices should have a block size, after all. This defaults to PAGE_SIZE if no size is specified.
2019-08-02	Kernel: mount system call (#396)	Jesse
	It is now possible to mount ext2 `DiskDevice` devices under Serenity on any folder in the root filesystem. Currently any user can do this with any permissions. There's a fair amount of assumptions made here too, that might not be too good, but can be worked on in the future. This is a good start to allow more dynamic operation under the OS itself. It is also currently impossible to unmount and such, and devices will fail to mount in Linux as the FS 'needs to be cleaned'. I'll work on getting `umount` done ASAP to rectify this (as well as working on less assumption-making in the mount syscall. We don't want to just be able to mount DiskDevices!). This could probably be fixed with some `-t` flag or something similar.
2019-07-28	Kernel: Expand PATA driver to support multiple hard drives (#365)	Jesse
	The previous implementation of the PIIX3/4 PATA/IDE channel driver only supported a single drive, as the object model was wrong (the channel inherits the IRQ, not the disk drive itself). This fixes it by 'attaching' two `PATADiskDevices` to a `PATAChannel`, which makes more sense. The reading/writing code is presented as is, which violates the spec outlined by Seagate in the linked datasheet. That spec is rather old, so it might not be 100% up to date, though may cause issues on real hardware, so until we can actually test it, this will suffice.
