Automatically print written but unread globals Make nodwf test passed when CONFIG_QUOTACTL unset Uses STAPCONF_DPATH_PATH instead of a kernel version check. Simplified "rpm" target a bit. Moved tar archive creation step from "rpm" target to "dist-gzip" target. remove support for "make dist" since git-archive does as well; Examples html files moved into subdir. 2008-08-25 David Smith <dsmith@redhat.com> ChangeLog Entries Robustness improvements for the stap client/server

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constructs At the moment, you can't specify probe module("scsi_mod").statement(*@drivers/scsi/scsi_lib.c:1443) because the compiler will fail with the above semantic error on the function scsi_end_bidi_request. It seems looking through the dwarf that this function is fully inlined and thus has no entrypc to catalogue. The solution therefore seems to simply return DWARF_CB_OK when we find such functions and continue cataloguing all the ones that do actually have non-inline versions.
