Hello,
Just found a big bug in the free space caching stuff that will result in
early ENOSPC. I'm working on fixing this bug, but it won't be until
tomorrow that I'll have it completely working, so for now make sure to
mount -o clear_cache so that it just clears the cache and doesn't use it.
NOTE: It doesn't cause problems other than early ENOSPC, you won't get
corruption or anything like that, tho you could possibly panic.
Sorry for the inconvenience. Thanks,
Any chance you could provide a little more information about which
kernels are affected? Is it any kernel with free space cache support (is
2.6.38.x included?) - and if so, do you plan on submitting the fix to
the stable kernel series?
Yeah it affects any kernel that has the free space cache feature, which I think
started in .37. Course you have to have specifically enabled it, so it's not a
huge problem. I've submitted a patch, but since it's currently an optional
feature I don't think it needs to go to stable. Thanks,
So it will have to wait for 2.6.39? If possible please push it for
inclusion it in the next stable of 2.6.38, as 2.6.39 is a few months
away and i wont risk an early RC for my system
Thanks
Josef
