| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Both the inline and non inline filtered function caches can lose functions. This happens because both of these caches are indexed by the entrypc. However, the vagaries of optimisation can actually cause us to end up with two functions with apparently the same entrypc (mainly because for inline functions, the entrypc has to be deduced from the range of addresses, which is nastily heuristic). A nice example of this is bsg_io_schedule. In my build of 2.6.26 it's a static function transformed to an inline by the compiler. The range deduction of its entrypc ends up being identical to that of bsg_release, so when I try to place a probe inside it, none of the function references actually refers to it. Since nothing ever actually makes use of this index, the fix is simple: don't use a map indexed on the entrypc, use a simple vector.
