Unmaintained example code is probably worse than useless.

Michael Brown
4e20d73bb5
Gave asynchronous operations approximate POSIX signal semantics. This
...
will enable us to cascade async operations, which is necessary in order to
properly support DNS. (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).
Anything other than HTTP is probably broken right now; I'll fix the others
up asap.

Add "dev" pointer in struct net_device to tie network interfaces back to a

Force natural alignment of data types in __table() macros. This seems to

Add RX quotas to the net device poll() method. This avoids the problem

of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left

Redefine TCP state to include "flags that have been sent" rather than
