267  * v2/3 protocol is unsigned 32 bit, but ILP32 kernel only allows 31 bits.
268  * In nfsv4, time value is a signed 64 bit, so needs to be checked for
269  * overflow as well (e.g. for setattr). So define the tunable as follows:
270  * nfs_allow_preepoch_time is TRUE if pre-epoch (negative) times are allowed
271  * and is FALSE (the default) otherwise. For nfsv2/3 this means that
272  * if negative times are allowed, the uint32_t time value is interpreted

274  * we use the value as is - except that if negative times are not allowed,
275  * we will not accept a negative value otw.

278  *

280  * FALSE, the maximum time value is INT32_MAX for 32-bit kernels and

282  * and the minimum is zero. Note that in that case, a 32-bit application
283  * running on a 64-bit kernel will not be able to access files with
284  * the larger time values.
285  * If nfs_allow_preepoch_time is TRUE, the maximum time value is INT32_MAX
286  * for both kernel configurations and the minimum is INT32_MIN.
287  *
288  * And for nfsv4 (int64_t):
289  *
290  * nfsv4 allows for negative values in the protocol, and has a 64-bit
291  * time field, so nfs_allow_preepoch_time can be ignored.
