/*
* At random times, the child self-immolates with a SIGKILL.
* This is the software equivalent of pulling the power cord.
* The parent then runs the test again, using the existing
- * storage pool, as many times as desired.
+ * storage pool, as many times as desired. If backwards compatability
+ * testing is enabled ztest will sometimes run the "older" version
+ * of ztest after a SIGKILL.
*
* (6) To verify that we don't have future leaks or temporal incursions,
* many of the functional tests record the transaction group number
* the transaction group number is less than the current, open txg.
* If you add a new test, please do this if applicable.
*
+ * (7) Threads are created with a reduced stack size, for sanity checking.
+ * Therefore, it's important not to allocate huge buffers on the stack.
+ *
* When run with no arguments, ztest runs for about five minutes and
* produces no output if successful. To get a little bit of information,
* specify -V. To get more information, specify -VV, and so on.
* You can ask more more vdevs [-v], datasets [-d], or threads [-t]
* to increase the pool capacity, fanout, and overall stress level.
*
- * The -N(okill) option will suppress kills, so each child runs to completion.
- * This can be useful when you're trying to distinguish temporal incursions
- * from plain old race conditions.
+ * Use the -k option to set the desired frequency of kills.
+ *
+ * When ztest invokes itself it passes all relevant information through a
+ * temporary file which is mmap-ed in the child process. This allows shared
+ * memory to survive the exec syscall. The ztest_shared_hdr_t struct is always
+ * stored at offset 0 of this file and contains information on the size and
+ * number of shared structures in the file. The information stored in this file
+ * must remain backwards compatible with older versions of ztest so that
+ * ztest can invoke them during backwards compatibility testing (-B).
