Description alarson 2005-09-22 17:02:04 MST
During User Guide reviews for the Agave kernel certification, this mutex error
status comment was found:

Lines 217-219 of mutexapi.sgm

<warning-desc>The mutexNotSchedulable return status should never
happen in the current system, since the system blocking time is
automatically computed by the Integration Tool.</warning-desc>

This appears to mean that the only way one could encounter this error would be
with an erroneous platform registry, perhaps as a result of altering the
registry after it was generated.  While we usually limit regchk tests to those
things that would crash the kernel, perhaps we could add a regchk rule here to
help the users with what would be an obvious mistake.


TRACK Comments:

05/18/2004 10:00:54 - mattd - No problem in the kernel, i.e. an incorrect mutex
setting that results in this error status only affects the using application,
not the operating system.  This is a feature request that will likely be
deferred until after the Agave certification - SAS classification Enhancement.

This is a desired feature that should be included in an upcoming release if time allows, and other updates are being made to mutexapi.sgm.  It is being taken off of HOLD for consideration for Kismet.
