Subject: Not all systems use st_[cm]tim field for ns resolution file timestamp
X-Git-Tag: v1.6.3-rc0~147^2~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=110c46a909;p=git.git

Not all systems use st_[cm]tim field for ns resolution file timestamp

Some codepaths do not still use the ST_[CM]TIME_NSEC() pair of macros
introduced by the previous commit but assumes all systems use st_mtim
and st_ctim fields in "struct stat" to record nanosecond resolution part
of the file timestamps.
