* Don't limit non-nested epoll pathsJason Baron2012-03-181-0/+4
| | | | | | | | | | | | | | | | | Commit 28d82dc1c4ed ("epoll: limit paths") that I did to limit the number of possible wakeup paths in epoll is causing a few applications to longer work (dovecot for one). The original patch is really about limiting the amount of epoll nesting (since epoll fds can be attached to other fds). Thus, we probably can allow an unlimited number of paths of depth 1. My current patch limits it at 1000. And enforce the limits on paths that have a greater depth.

| * sch_sfq: revert dont put new flow at the end of flowsEric Dumazet2012-03-161-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit d47a0ac7b6 (sch_sfq: dont put new flow at the end of flows) As Jesper found out, patch sounded great but has bad side effects. In stress situation, pushing new flows in front of the queue can prevent old flows doing any progress. Packets can stay in SFQ queue for unlimited amount of time. It's possible to add heuristics to limit this problem, but this would add complexity outside of SFQ scope. A more sensible answer to Dave Taht concerns (who reported the issued I tried to solve in original commit) is probably to use a qdisc hierarchy so that high prio packets dont enter a potentially crowded SFQ qdisc.

Add the syscall numbers to the already existing i386 and x86_64 blocks in perf.h, and also provide empty include file stubs. With this patch perf builds and works fine on 5 years old user-space as well.
