| Doc Text: |
VDSO (Virtual Dynamically-linked Shared Object) kernel variables must be exported in vextern.h, otherwise they end up as undefined pointers. When calling the VDSO gettimeofday() function in Red Hat Enterprise Linux 5, a missing declaration lead to a segmentation fault. With this update, the sysctl_vsyscall system call is properly exported and segmentation faults no longer occur.
