244 * we should accept or reject an unsigned 32-bit time value. Time value in NFS
245 * v2/3 protocol is unsigned 32 bit, but ILP32 kernel only allows 31 bits.
246 * In nfsv4, time value is a signed 64 bit, so needs to be checked for
247 * overflow as well (e.g. for setattr). So define the tunable as follows:
248 * nfs_allow_preepoch_time is TRUE if pre-epoch (negative) times are allowed
249 * and is FALSE (the default) otherwise. For nfsv2/3 this means that
250 * if negative times are allowed, the uint32_t time value is interpreted
251 * as a signed int, otherwise as a large positive number. For nfsv4,
252 * we use the value as is - except that if negative times are not allowed,
253 * we will not accept a negative value otw.

256 *
257 * If nfs_allow_preepoch_time is

260 * and the minimum is zero. Note that in that case, a 32-bit application
261 * running on a 64-bit kernel will not be able to access files with
262 * the larger time values.
263 * If nfs_allow_preepoch_time is TRUE, the maximum time value is INT32_MAX
264 * for both kernel configurations and the minimum is INT32_MIN.
265 *
266 * And for nfsv4 (int64_t):
267 *
268 * nfsv4 allows for negative values in the protocol, and has a 64-bit
269 * time field, so nfs_allow_preepoch_time can be ignored.
