| H A D | watchdog_perf.c | 6ea0d04211a7715a926f5dca4aa1065614fa64da Fri May 19 19:18:31 CEST 2023 Douglas Anderson <dianders@chromium.org> watchdog/perf: rename watchdog_hld.c to watchdog_perf.c
The code currently in "watchdog_hld.c" is for detecting hardlockups using
perf, as evidenced by the line in the Makefile that only compiles this
file if CONFIG_HARDLOCKUP_DETECTOR_PERF is defined. Rename the file to
prepare for the buddy hardlockup detector, which doesn't use perf.
It could be argued that the new name makes it less obvious that this is a
hardlockup detector. While true, it's not hard to remember that the
"perf" detector is always a hardlockup detector and it's nice not to have
names that are too convoluted.
