    SubjectRe: [EXT4 set 4][PATCH 1/5] i_version:64 bit inode version

    It just occurred to me:

    If i_version is 64bit, then knfsd would need to be careful when
    reading it on a 32bit host. What are the locking rules?

    Presumably it is only updated under i_mutex protection, but having to
    get i_mutex to read it would seem a little heavy handed.

    Should it use a seqlock like i_size?
    Could we use the same seqlock that i_size uses, or would we need a
    separate one?
