linux.git/drivers/misc, branch v2.6.26-rc2 Linux kernel source tree kgdb: 1000 loops for the single step test in kgdbts 2008-05-05T12:13:21+00:00 Jason Wessel jason.wessel@windriver.com 2008-04-24T21:57:23+00:00 7cfcd985d36031459cc64e3843ea36a4d801097d The single step test is not terribly costly and it should be able to pass at 1000 loops successfully in under 1 second. A non-kgdb timing regression was found using this test, but it did not occur frequently because by default the test was only executed a single time. This patch changes the default for the single step test to 1000 iterations and allows for individual configuration of the single step test to further exercise the kgdb subsystem when needed.

Remove proc_root export.  Creation and removal works well if parent PDE is
supplied as NULL -- it worked always that way.

So, one useless export removed and consistency added, some drivers created
PDEs with &proc_root as parent but removed them as NULL and so on.

drivers/misc: elide a non-zero test on a result that is never 0

The function thermal_cooling_device_register always returns either a valid
pointer or a value made with ERR_PTR, so a test for non-zero on the result
will always succeed.

The problem was found using the following semantic match.
