bbc658930a Passing va_list in syscall does not work. Temporarily moved syslog and lowsyslog into kernel code and access via a system call. Need to revisit. Will probably need to move all of syslog back from fs/syslog to libc/syslog 2014-10-08 20:12:52 -06:00

f8ed7323c0 make standard syslog and vsyslog POSIX compliant (also modify non-standard syslog functions for compatibility). This will break a lot of things until ALL usage of syslog is updated to use the modified interfaces 2014-10-08 09:44:15 -06:00
