Previously, certain error check functions like IsAlreadyStopped returned true if the error was ERROR_PROC_NOT_FOUND. Based on the comment in the file, this was intended to be used to indicate a case where the process could not be found. However, it seems this may have been added erroneously. ERROR_PROC_NOT_FOUND is actually typically used to mean that a _procedure_ lookup failed, and has nothing to do with processes. The original change[1] to check against ERROR_PROC_NOT_FOUND was made five years ago, and did not contain much information on why this error would be returned. We are removing this now based on several factors: - We are not aware of any condition where HCS would intentionally return ERROR_PROC_NOT_FOUND to indicate a condition "process does not exist". - There is an issue where HcsShutdownComputeSystem sometimes returns ERROR_PROC_NOT_FOUND due to something failing internally. The current error checks are causing this to be treated as "the container has already exited", causing moby to not properly stop the container via HcsTerminateComputeSystem. This change leaves the definition for ErrProcNotFound in the code, as it may be used by external callers, but fixes its comment.
