I will try to implement the feature. I created the patchset for implementing the above feature. Any comments/patches are welcome. --- [PATCH 0/5] make '-x'/'-i' option unnecessary for re-filtering. makedumpfile v1.3.4 can read a dumpfile which is kdump-compressed format instead of /proc/vmcore and re-filter it. When re-filtering, it is necessary to specify '-x'/'-i' option. If not specifying, makedumpfile fails like the following: # ./makedumpfile -c -d 3 vmcore vmcore.1 ... The dumpfile is saved to vmcore.1 ... # # /makedumpfile -c -d 31 vmcore.1 vmcore.2 vmcore.1 doesn't contain vmcoreinfo. Specify '-x' option or '-i' option. Commandline parameter is invalid. Try `makedumpfile --help' for more information. # For usability, this patchset makes '-x'/'-i' option unnecessary for re-filtering.
