9The need for a document like this one became apparent in the
10linux-kernel mailing list as the same questions, asking for pointers
11to information, appeared again and again.
12
13Fortunately, as more and more people get to GNU/Linux, more and more
14get interested in the Kernel. But reading the sources is not always
15enough. It is easy to understand the code, but miss the concepts, the
16philosophy and design decisions behind this code.
17
18Unfortunately, not many documents are available for beginners to
19start. And, even if they exist, there was no "well-known" place which
20kept track of them. These lines try to cover this lack.
21
22PLEASE, if you know any paper not listed here or write a new document,
23include a reference to it here, following the kernel's patch submission
24process. Any corrections, ideas or comments are also welcome.
25
26All documents are cataloged with the following fields: the document's
27"Title", the "Author"/s, the "URL" where they can be found, some
28"Keywords" helpful when searching for specific topics, and a brief
29"Description" of the Document.

264 how your Operating System allows you to manage a large number of
265 open files (file descriptors in UNIX/POSIX, or FDs) in your
266 application. You want the OS to notify you when FDs become active
267 (have data ready to be read or are ready for writing). Ideally you
268 want a mechanism that is scalable. This means a large number of
269 inactive FDs cost very little in memory and CPU time to manage".

399 writing, and several different facilities have been provided for
400 different situations. We also investigate the complex topic of
401 DMA*.
