218  * we should accept or reject an unsigned 32-bit time value. Time value in NFS
219  * v2/3 protocol is unsigned 32 bit, but ILP32 kernel only allows 31 bits.
220  * In nfsv4, time value is a signed 64 bit, so needs to be checked for
221  * overflow as well (e.g. for setattr). So define the tunable as follows:
222  * nfs_allow_preepoch_time is TRUE if pre-epoch (negative) times are allowed
223  * and is FALSE (the default) otherwise. For nfsv2/3 this means that
224  * if negative times are allowed, the uint32_t time value is interpreted
225  * as a signed int, otherwise as a large positive number. For nfsv4,
226  * we use the value as is - except that if negative times are not allowed,
227  * we will not accept a negative value otw.
228  *
229  * So for nfsv2/3 (uint32_t):
230  *
231  * If nfs_allow_preepoch_time is
232  * FALSE, the maximum time value is INT32_MAX for 32-bit kernels and
233  * UINT32_MAX for 64-bit kernels (to allow times larger than 2038)
234  * and the minimum is zero. Note that in that case, a 32-bit application
235  * running on a 64-bit kernel will not be able to access files with
236  * the larger time values.
237  * If nfs_allow_preepoch_time is TRUE, the maximum time value is INT32_MAX
238  * for both kernel configurations and the minimum is INT32_MIN.
239  *
240  * And for nfsv4 (int64_t):
241  *
242  * nfsv4 allows for negative values in the protocol, and has a 64-bit
243  * time field, so nfs_allow_preepoch_time can be ignored.
