misc: vmw_balloon: Remove braces to fix build for clang.

2013-08-28T04:51:21+00:00

Based on a patch from: PaX Team  in a mailing
list message at:
	http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120507/142707.html

Clang chokes on the notation "inl (%dx)" but works for "inl %dx"; GNU as accepts both forms.

vmw_balloon: fix for a -Wuninitialized warning

2012-02-03T00:28:13+00:00

Fix for a -Wuninitialized compiler warning. Changed return value of
vmballoon_send_lock_page() from bool to int to be able to distinguish
between the error cases to avoid uninitialized use of hv_status in
vmballoon_reserve_page()

drivers/misc/vmw_balloon.c: determine page allocation flag can_sleep outside loop

2011-11-02T23:07:03+00:00

In vmballoon_reserve_page(), flags has been passed from the callee
function (vmballoon_inflate here).  So, we can determine can_sleep outside
the loop.

Vmware balloon: switch to using sysem-wide freezable workqueue

2011-07-26T23:49:45+00:00

With the arrival of concurrency-managed workqueues there is no need for
our driver to use dedicated workqueue; system-wide one should suffice just
fine.

workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'

2011-02-16T16:48:59+00:00

There are two spellings in use for 'freeze' + 'able' - 'freezable' and
'freezeable'.  The former is the more prominent one.  The latter is
mostly used by workqueue and in a few other odd places.  Unify the
spelling to 'freezable'.

VMware balloon: stop locking pages when hypervisor tells us enough

2011-01-13T16:03:22+00:00

When hypervisor decides to decrease target balloon size while the balloon
driver tries to lock pages hypervisor may respond with
VMW_BALLOON_PPN_NOTNEEDED.  Use this data and immediately stop reserving
pages and wait for the next update cycle to fetch new target instead of
continuing trying to lock pages until size of refused list grows above
VMW_BALLOON_MAX_REFUSED (16) pages.

As a result the driver stops bothering the hypervisor with its attempts to
lock more pages that are not needed anymore.  Most likely next order from
hypervisor will be to reduce ballon size anyway.

It is a small optimization.

vmware balloon: rename module

2010-09-23T00:22:38+00:00

In an effort to minimize customer confusion we want to unify naming
convention for VMware-provided kernel modules.  This change renames the
balloon driver from vmware_ballon to vmw_balloon.

We expect to follow this naming convention (vmw_) for all
modules that are part of mainline kernel and/or being distributed by
VMware, with the sole exception of vmxnet3 driver (since the name of
mainline driver happens to match with the name used in VMware Tools).
