Subject: [PULL REQUEST] fix for v.large RAID5 with v.small chunks
Date: Wed, 21 Apr 2010 15:17:21 +1000 [thread overview]
Message-ID: <19406.35425.223934.477541@notabene.brown> (raw)
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
