Description

From zhao...@google.com on December 27, 2012 12:45:29

Different Windows have different set of system calls, the client may need know the os version, e.g. running_on_Win7_or_later running_on_Win7SP1_or_later running_on_Vista_or_later get_windows_version

It is also true for Linux.

It looks like drsyscall should be the one provides such functions.

Original issue: http://code.google.com/p/drmemory/issues/detail?id=1106

Contributor guide

Research direction
Investigate the existing drsyscall module to understand how it handles Windows syscall availability. Then determine the equivalent Linux kernel version detection method, such as using `uname` or parsing `/proc/sys/kernel/osrelease`. Implement a function that returns the Linux kernel version and a helper to check if a syscall is available based on that version.
