* Check for time overflow using a kernel tunable to determine whether
* we should accept or reject an unsigned 32-bit time value. Time value in NFS
* v2/3 protocol is unsigned 32 bit, but ILP32 kernel only allows 31 bits.
* In nfsv4, time value is a signed 64 bit, so needs to be checked for
* overflow as well (e.g. for setattr). So define the tunable as follows:
* nfs_allow_preepoch_time is TRUE if pre-epoch (negative) times are allowed
* and is FALSE (the default) otherwise. For nfsv2/3 this means that
* if negative times are allowed, the uint32_t time value is interpreted
* as a signed int, otherwise as a large positive number. For nfsv4,
* we use the value as is - except that if negative times are not allowed,
* we will not accept a negative value otw.
*
* So for nfsv2/3 (uint32_t):
*
* If nfs_allow_preepoch_time is
* FALSE, the maximum time value is INT32_MAX for 32-bit kernels and
* UINT32_MAX for 64-bit kernels (to allow times larger than 2038)
* and the minimum is zero. Note that in that case, a 32-bit application
* running on a 64-bit kernel will not be able to access files with
* the larger time values.
* If nfs_allow_preepoch_time is TRUE, the maximum time value is INT32_MAX
* for both kernel configurations and the minimum is INT32_MIN.
*
* And for nfsv4 (int64_t):
*
* nfsv4 allows for negative values in the protocol, and has a 64-bit
* time field, so nfs_allow_preepoch_time can be ignored.
