> Most of the VFS layer, with so many optimizations for spinning rust. Right out. You already aren't running 'em! Also, that's the block device layer, not the VFS layer. The VFS is the bit between the syscall interface and the concrete FS (which then in turn works with the block layer, if you are using a block device). Don't go signing the death warrant for something you clearly don't understand.
