The various macros to do checks in system call handlers all implictly would generate a kernel oops if a check failed. This is undesirable for a few reasons: * System call handlers that acquire resources in the handler have no good recourse for cleanup if a check fails. * In some cases we may want to propagate a return value back to the caller instead of just killing the calling thread, even though the base API doesn't do these checks. These macros now all return a value, if nonzero is returned the check failed. K_OOPS() now wraps these calls to generate a kernel oops. At the moment, the policy for all APIs has not changed. They still all oops upon a failed check/ The macros now use the Z_ notation for private APIs. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
