* ASSERTION:
* Checks that setting "bufresize" to "auto" will cause buffer
* allocation to succeed, even for large principal buffer sizes.
*
* SECTION: Buffers and Buffering/Buffer Resizing Policy;
* Options and Tunables/bufsize;
* Options and Tunables/bufresize
*
* NOTES:
* On some small memory machines, this test may consume so much memory
* that it induces memory allocation failure in the dtrace library. This
* will manifest itself as an error like one of the following:
*
* dtrace: processing aborted: Memory allocation failure
* dtrace: could not enable tracing: Memory allocation failure
*
* These actually indicate that the test performed as expected; failures
* of the above nature should therefore be ignored. If 32-bit libdtrace
* is used to execute this test on a 64-bit kernel, the failure mode
* becomes exceedingly likely because the kernel may be able to allocate
* a huge hunk of memory that then requires the client to match it with
* a malloc that exhausts the remainder of its 4GB address space. For
* this reason, we no-op the test for 32-bit clients using an ifdef.
