Fedora dracut-044-75 release has all the component needed to support
rebuild in case of watchdog state change. Therefore sending these patches
for inclusion in kexec-tools.
Please note that these patches should only be added in those fedora
versions which has dracut version dracut-044-75 or latter. Anyway, we
already have dependency specified in spec file as well.
Most of the rebuild test cases have been mentioned in the commit log of 2/5.
Other than that, I have also tested effect of adding either "-o watchdog"
or "-a watchdog" or none of them. They have been found to behave as
expected. So, when we pass -o watchdog in dracut_args, it does not include
kernel watchdog module whether state is active or inactive. In all other
cases, it adds kernel module only when state is active.
Changes since V3:
- Now we only look for "-o watchdog" in dracut_args. If it is not passed
then we add "-a watchdog" in dracut_args by default.
- Notes in howto modified accordingly
Changes since V2:
- Removed NOWDT argument. Using dracut_args instead.
- Removed man page update. Included notes in howto
- Reorganized mkdumprd code for watchdog dracut argument addition
Changes since V1:
- Removed patch 4/5 which was updating kdumpctl man page.
- Added all necessary information in kdump.conf man page (patch 2/4).

watchdog is always added, it addes extra wdctl and maybe some libraries
but consider the size is small, we can leave with it.
For the series.
