vmware balloon: clamp number of collected non-balloonable pages

2010-06-04T22:21:44+00:00

Limit number of accumulated non-balloonable pages during inflation cycle,
otherwise there is a chance we will be spinning and growing the list
forever.  This happens during torture tests when balloon target changes
while we are in the middle of inflation cycle and monitor starts refusing
to lock pages (since they are not needed anymore).

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58+00:00

I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

lktdm: add support for hardlockup, softlockup and hung task crashes

2010-05-27T16:12:54+00:00

This adds three new types of kernel "crashes" in the lkdtm driver to
trigger hardlockups, softlockups and task hung states at will.

The first two are useful to test the new generic lockup detector and check
its further regressions.  The latter one is a bonus to check the hung task
detector regressions even though it's not currently in rework.
