[PATCH] fs: make i_generation a u64

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

 



Btrfs stores generation numbers as 64bit numbers, which means we have to
carry around a u64 in our incore inode in addition to setting i_generation.
So convert to a u64 so btrfs can kill it's incore generation.  Thanks,
