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 The following changes since commit 85341c61361cc45a9cc0e11c01e8f4479ef460ac: Linus Torvalds (1): Merge branch 'core-fixes-for-linus' of git://git.kernel.org/.../tip/linux-2.6-tip are available in the git repository at: git://neil.brown.name/md/ for-linus NeilBrown (1): md/raid5: allow for more than 2^31 chunks. drivers/md/raid5.c | 19 +++++++------------ 1 files changed, 7 insertions(+), 12 deletions(-)
