To accomplish this, I've investigated top-down from the [[hurd/translator/ext2fs]] translator to Mach. This section contains the main nodes that data passes through. This section is probably unnecessary to implement the prefetcher in Mach, however it is always interesting to understand how things work so we can notice when they get broken. This is based on my understanding of the system and is probably imprecise. Refer to the manuals of both Hurd and Mach for more detailed information. ### Pagers -Pagers are implemented in libpager and provide abstracted access to Mach's [[VM]]. A pager is a struct that contains callback function references. These are used to actually access the storage. In the case of FS translators, like ext2fs, the pager uses libstore to acess the underlying hardware. +Pagers are implemented in libpager and provide abstracted access to Mach's [[microkernel/mach/virtual address space]].
