Subject: vfs: utimensat(): ignore tv_sec if tv_nsec == UTIME_OMIT or UTIME_NOW
From: Michael Kerrisk <mtk.manpages@xxxxxxxxxxxxxx>
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.
