Subject: Adjust to TIMESPEC_HZ renaming
X-Git-Tag: emacs-27.0.90~4435
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=ef93983344e748124ac9bc218700cee14a0df947;p=emacs.git

Adjust to TIMESPEC_HZ renaming

Adjust to lib/timespec.h’s renaming of TIMESPEC_RESOLUTION and
LOG10_TIMESPEC_RESOLUTION to TIMESPEC_HZ and
LOG10_TIMESPEC_HZ.  The old names were misnomers.
All uses changed.
