Some notes about names used for syscalls and args:
- For the --trace-syscalls=yes output, we use the sys_foo() name to avoid
- Also, for error messages the arg names are mostly taken from the man
pages (even though many of those man pages are really for glibc
- functions of the same name), rather than from the Linux kernel source,
+ functions of the same name), rather than from the OS kernel source,
for the same reason -- a user presented with a "bogus foo(bar)" arg
will most likely look at the "foo" man page to see which is the "bar"
arg.
