[PULL REQUEST] fix for v.large RAID5 with v.small chunks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,
 I wonder if you would pull this fix for 2.6.33.
 If you have a very large RAID5 - say 8TB, quite easy these days -
 with very small chunks - say 4K, not common but quite possible -
 then you can get more than 2^31 chunks so storing the number of
 chunks in an 'int' doesn't really work.

Thanks,
NeilBrown
