Version:           3.5.0
OS:                Linux

epoll_ctl, epoll_wait, sendfile, sendgroups are missing from setup_post_syscall_table for Linux - as they all don't return pointers i simply added them at alphabeticaly halfway fitting places.

here is the patch that if applied allows to inspect lighttpd:

Reproducible: Always

Steps to Reproduce:
Simply start valgrind --tool=exp-ptrcheck lighttpd - it'l bail out every time with "the impossible happend"...



I don't know if it's necessary to protect the new ADD-Lines with #if defined(...) / #endif - so maybe the patch is incomplete - but the changes are
