Hi. makedumpfile version 1.0.8 is released. Please test it. Your opinions/comments are welcome.
Explanation of makedumpfile: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore. You can specify the kind of unnecessary pages with dump_level. If you want to shorten the size further, enable the compression of the page data. Changelog: - linux-2.6.19 support. On linux-2.6.18 or before, the release information could be gotten from the symbol "system_utsname". But on linux-2.6.19, it can be done from the symbol "init_uts_ns". A new makedumpfile check both symbols for the release information. - i386 SPARSEMEM support. - Add the debug option(-D). If running makedumpfile with -D option, makedumpfile shows the debug information. If the problem happens, please run it with this option. - Passing the buffer size properly to compress2() This patch was provided by Bob Montgomery, Thanks. - Other corrections - Add the check method for getting the node descriptor. - Add the comment about the bitmap length. - Get the number of ZONEs dynamically.
