[patch for 2.6.26 1/4] vfs: utimensat(): ignore tv_sec if tv_nsec == UTIME_OMIT or UTIME_NOW
The POSIX.1 draft spec for utimensat() says that if a times[n].tv_nsec field is UTIME_OMIT or UTIME_NOW, then the value in the corresponding tv_sec field is ignored. See the last sentence of this para, from the spec: If the tv_nsec field of a timespec structure has the special value UTIME_NOW, the file's relevant timestamp shall be set to the greatest value supported by the file system that is not greater than the current time. If the tv_nsec field has the special value UTIME_OMIT, the file's relevant timestamp shall not be changed. In either case, the tv_sec field shall be ignored. However the current Linux implementation requires the tv_sec value to be zero (or the EINVAL error results). This requirement should be removed.
