The Buffer Cache

 

[Here, it should be explained briefly how ll_rw_block() is called, about getblk() and bread() and breada() and bwrite(), etc. A real explanation of the buffer cache is reserved for the VFS reference section, where something on the complexity order of Bach's treatment of the buffer cache should exist.

For now, we assume that the reader understands the concepts behind the buffer cache. If you are a reader and don't, please email me and I'll help you, which will also help me put my thoughts together for that section.]
