[PATCH 2/2] [v2] btrfs: use timespec64 for i_otime

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

 



While the regular inode timestamps all use timespec64 now, the
i_otime field is btrfs specific and still needs to be converted
to correctly represent times beyond 2038.
