The ZFS on-disk format stores each inode's generation ID as a 64 bit number on disk and in-core. However, the Linux kernel's inode is only a 32 bit number. In most places, the code handles this correctly, but the cast is missing in zfs_rezget(). For many pools, this isn't an issue since the generation ID is computed as the current txg when the inode is created and many pools don't have more than 2^32 txgs. For the pools that have more txgs, this issue causes any inode with a high enough generation number to report IO errors after a call to "zfs rollback" while holding the file or directory open. This patch simply adds the missing cast.
