Using pipe pools makes pipe management a lot easier. It also allows to remove quite a bunch of #ifdefs in areas which depended on the presence or not of support for kernel splicing. The buffer now holds a pointer to a pipe structure which is always NULL except if there are still data in the pipe. When it needs to use that pipe, it dynamically allocates it from the pipe pool. When the data is consumed, the pipe is immediately released. That way, there is no need anymore to care about pipe closure upon session termination, nor about pipe creation when trying to use splice(). Another immediate advantage of this method is that it considerably reduces the number of pipes needed to use splice(). Tests have shown that even with 0.2 pipe per connection, almost all sessions can use splice(), because the same pipe may be used by several consecutive calls to splice().
