@ -151,6 +151,23 @@ Changelog for series 0.1a:
The old stable branch mars 0.1.y is EOL,
now fully superseeded by this branch.
mars0.1astable131
* Major fix: long-standing race condition on aspect {de,}allocation.
Was triggering extremely rarely and was very hard to
reproduce, but it could lead to rare stacktraces and
to rare kernel hangs.
I am not 100% sure to have fixed it fully, but massive testing
over a long time tells me that it has _at least_ improved.
Further stresstest improvements after safeguarding potentially
misleading callbacks from aio & co over shared kernel files,
where their shared pagecache cannot distinguish different callers.
Possibly more improvements might appear in future releases.
This will take a lot of time for extreme stress-testing.
* Minor safeguard: better safeguard of indirect calls via mb().
Theoretically, this should be unnecessary. But I saw some
extremely rare effects (only at a certain hardware class),
so I prefer stability over maximum performance.
mars0.1astable130
* Minor improvement: marsadm now compensates race between
emergency mode removal and invalidate.
